## latex,

emulsion of a polymer (e.g., rubberrubber,
any solid substance that upon vulcanization becomes elastic; the term includes natural rubber (caoutchouc) and synthetic rubber. The term elastomer is sometimes used to designate synthetic rubber only and is sometimes extended to include caoutchouc as well.
) in water (see colloidcolloid
[Gr.,=gluelike], a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture is also called a colloidal system, colloidal solution, or colloidal dispersion.
). Natural latexes are produced by a number of plants, are usually white in color, and often contain, in addition to rubber, various gums, oils, and waxes. Balata, caoutchouc, chicle, and gutta-percha are produced from natural latexes. Synthetic latexes may be prepared in two ways: the polymer may be prepared as an emulsion (emulsion polymerization), or the dry, powdered polymer may be dispersed in water. Both natural and synthetic latexes are widely used, especially in the production of rubber goods. Latex paints, sometimes called rubber-base paints, consist of a latex colored by the addition of a pigment.

## Latex

the transparent, milk-white, yellowish brown, yellow, or orange contents of the latex vessels of plants.

A number of plants of the families Euphorbiaceae, Moraceae, and Compositae hold large amounts of latex, which contains (dissolved or suspended) carbohydrates, proteins, glycosides, salts, and essential oils. The characteristic components of the latex of gutta-percha-yielding and rubber-yielding plants are resins, gutta, and natural rubber. The latex of certain plants of the poppy family (Papaveraceae) contains large quantities of alkaloids. The latex of the papaya yields the enzyme papain.

## latex

[′lā‚teks]
(materials)
Milky colloid in which natural or synthetic rubber or plastic is suspended in water.
An elastomer product made from latex.

## latex

An emulsion of finely dispersed particles of natural or synthetic rubber or plastic materials in water.

## latex

1. a whitish milky fluid containing protein, starch, alkaloids, etc., that is produced by many plants. Latex from the rubber tree is used in the manufacture of rubber
2. a suspension of synthetic rubber or plastic in water, used in the manufacture of synthetic rubber products, etc.

## LaTeX

(language, text, tool)
(Lamport TeX) Leslie Lamport <lamport@pa.dec.com>'s document preparation system built on top of TeX. LaTeX was developed at SRI International's Computer Science Laboratory and was built to resemble Scribe.

LaTeX adds commands to simplify typesetting and lets the user concentrate on the structure of the text rather than on formatting commands.

BibTeX is a LaTeX package for bibliographic citations.

Lamport's LaTeX book has an exemplary index listing every symbol, concept and example in the book. The index in the, now obsolete, first edition includes (on page 221) the mysterious entry "Gilkerson, Ellen, 221". The second edition (1994) has an entry for "infinite loop" instead.

## LaTeX

(LAmport TeX) A document preparation system based on the TeX language developed by Leslie Lamport at SRI International. LaTeX provides a macro language for TeX that lets the user concentrate on the logical structure of the document rather than the format codes. See TeX.

To evaluate the reason for stability change with different alcohols yet further, the time-dependent behavior of the latex was investigated by the transmission profile measurements using a Turbiscan LAB (Formulaction, Toulouse, France) every minute for 30 min at 30[degrees]C.
Seven hundred twenty-three subjects attending their 2-yearly occupational health visit according to legislative decree 81 [28] (i.e., year 3 and 6 medical students, and year 1 and 3 nursing students) and having had occupational exposure to latex for less than 5 years through the regular use of latex gloves (i.e., at least once or twice a week) were invited to participate in a baseline screening in accordance with the guidelines for health monitoring established by the occupational physician.
Questions included sex, age, frequency of latex glove use, exposure (hours of glove use per day up to 3 days before the interview) and information on family and personal histories of allergic disorders, exposure to other latex items (household cleaning gloves, balloons, diaphragm, condoms), number of times a day that hands were washed, and exposure to chemical irritants at work.

In this article we explained our experience with two different anaesthetic techniques performed on the same patient who had latex hypersensitivity reaction and had undergone myomectomy operation twice in 5 years.
An important gap in the performance of architectural waterborne paints is caused by the use of low-VOC coalescents with high molecular weights and boiling points that do not evaporate completely from the latex films and negatively affect the hardness evolution, dirt pick-up resistance, and the overall durability of the final paints.
Another angle which shows the shift of the latex sector from North America and Europe to Asia, where NR is mostly produced, is to look at the share of latex imports to total NR imports.
But the travel agency has ignored it.' Hana Tour takes a substantial commission _ effects 65 percent _ on every latex product sold to tourists, the source noted.
The addition of the PPh can effectively act as a coalescing aid for the latexes film polymer; when we add less than 5.00 wt.% amount of PPh to the acrylic latexes, it has little influence on the latex system but can effectively lower its films [T.sub.g] and MFFT, and it can also change the latex water evaporation rate and transform the latex deformation mechanism.
The hollow latex spheres are prepared by dispersing the as-prepared latex suspension with PS core-PMMA/PAA shell into the solvent of n-hexane, which is a good solvent of PS core but poor solvent of PMMA/PAA shell.
