Sulfosuccinates are similar to alkyl sulfonates and are based on the petro chemically derived maleic acid anhydride
Thus, the present study deals with the surface modification of bagasse paper sheet by grafting with long hydrocarbon chain through heterogeneous esterification with fatty acid anhydride
The present invention is a thermoplastic elastomer composition comprising an ethylene-vinyl alcohol copolymer and a modified rubber dispersed in the ethylene-vinyl alcohol copolymer, wherein the modified rubber has an acid anhydride
group or epoxy group and is dynamically crosslinked by a compound having at least two amino groups.
Fewer people in Britain are affected by the condition but, still, our hangovers do vary greatly from one person to another, which is at least in part due to a nasty toxic molecule called acid anhydride
Absolute ethanol, ammonia solution, maleic acid anhydride
(MAA), divinylbenzene (DVB), and N-methyl-2-pyrrolidone (NMP) were used as received without further purification.
W = 187 g/mol) with methylbicyclo-[2,2,l]heptene-2,3-dicarboxylic acid anhydride
(NMA, supplied by Aldrich Chem.
A granulate of wood or some other cellulose-containing material, pieces or particles of said material being at least partially esterified with 10-50% of a dicarboxylic acid anhydride
and then impregnated with 2-25% of a polyol, the granulate being stable in storage and being possible to hot press or hot form later.
Acetic Anhydride, also known as ethanoic anhydride, is the simplest isolatable acid anhydride
, produced from acetic acid.
has obtained a patent for a method for imparting defoaming property to a baking finish type topcoat paint containing an acid anhydride
curing agent, a melamine resin curing agent or a glycidyl-containing acrylic resin/acid anhydride
curing agent for motor vehicles comprised of the step of adding a copolymer of 2%-50% by weight of a polymerizable monomer capable of forming a copolymer having isocyanate groups which can react with a binder resin in thermosetting paint or a polymerizable monomer capable of forming a copolymer having groups capable of producing isocyanate groups which can react with a binder resin in thermosetting paint during baking step of the same paint, and 98%-50% by weight other monomer or polymer reactable with the polymerizable monomer or to the topcoat paint.
Highly suitable polycarboxylic acids are, for instance, phthalic acid anhydride
, terephthalic acid anhydride
, trimellitic acid, adipic acid, and maleic acid.
Orthoxylene is a compound used for making phthalic anhydride, an aromatic acid anhydride
The thermally and radiation curable powder coatings are comprised of at least one resin A having epoxy groups and at least one compound B having acid and/or acid anhydride
