During the drafting process, describing and protecting alternatives is where the inventor's knowledge of the invention is critical--what is the length of the alkylene
chain such that the surfactant still retains activity?
Hydrophobically Modified Alkylene
Oxide Urethane Polymer, U.
Manufactured by the Japanese company Tokai Optical, this material, which has the ingredient Alkylene
Sulfide Polymer, is currently the highest available refractive index plastic, and is supplied by several UK laboratories.
3]  >45%,~7O% amylose [50-52] Starch ester, modified with alkylene
oxide  Poly(ethylene-co-acrylic acid), poly(ethylene-vinyl [54, 55] alcohol), [Na.
The NGL/olefins mixture will fractionated into ethane-ethylene, propane, polymer-grade propylene, normal butane, an alkylene
feed and condensate, according to reports.
It is composed of a blend of Alkylene
Oxide Copolymers that are commonly used in the medical field.
Uwe Kirchgaissner, comprises the businesses for cracker products and industrial gases as well as alkylene
oxides and glycols in Europe.
Reaction with alkylene
oxides has yielded some decay and termite resistance (Rowell and Gutzmer 1975, Rowell et al.
Polymer quenchants, such as PAG (poly alkylene
glycol)based fluids, have been used for many years to provide improved distortion control and cracking in various heat-treating operations.
In other technical presentations, George Totten, Union Carbide, discussed the effects and controls required when using polyethylene alkylene
glycol in an aluminum heat treating quenchant bath.
groups, where X is NR, and where [pi] is a polymer chain.
7,611,696 B2; DSM IP Assets, The Netherlands, has patented a UVA screening composition comprised of the general formula I or II: wherein m is 1 or 2; R1 and R2 are identical or different electron-withdrawing groups, or one of R1 and R2 is hydrogen and the other of R1 and R2 is an electron-withdrawing group; R3, R4, R5, and R6 are, independently, hydrogen, alkyl, cycloalkyl or aryl; R3 and R5 and/or R4, and R6 taken together with the carbon atoms to which they are attached, form a 5 or 6 membered ring which is unsubstituted or substituted with one to four alkyl, cycloalkyl or alkoxy groups; X is a moiety R7, when m is 1, and is alkylene
or poly(oxyalkylene) when m is 2; and R7 is hydrogen, alkyl, cycloalkyl, alkoxyalkyl or aryl; and a topically applicable, cosmetically acceptable carrier.
