摘要:
The invention relates to polymers containing units of the structure (A) and (B) or (B-1) or (B-2), or mixtures of A with more than one of B, B-1 and B-2; wherein R and R are each independently C1 to C18 alkyl; R is oxygen, sulfur or -NR -; R is hydrogen or lower alkyl; R is alkylene having from 3 to 6 carbon atoms, optionally mono- or di- substituted with lower alkyl; W is hydrogen, -NH4, an alkali metal or an alkaline earth metal; Y is alkylene; Z is hydrogen, -NH4, an alkali metal or an alkaline earth metal or mixtures thereof; X is lower alkyl, a hydroxy phenyl radical or mixtures thereof; t has a value of from 2 to 8 and m, m', m" and n independently have a value of from 30 to 3,500 and n represents at least 5 mole percent of the polymeric product. The invention is also related to the synthesis of the above polymers and to their use as superior adhesives which have significantly improved bond strength.
摘要:
A controlled release, drug-delivery tableted composition comprising, by weight, an uncrosslinked or crosslinked polymer of (a) about 5-40 % of a vinyl amide, (b) about 10-70 % of (meth)acrylic acid, (c) about 5-40 % of a long chain alkyl (meth)acrylate or acrylamide, and (d) about 0-60 % of a lower alkyl (meth)acrylate, and a pharmaceutical medicament.
摘要:
A low VOC (volatile organic compounds) hair spray composition having a combination of desirable user performance characteristics is described herein. The hair fixative resin in the composition is a terpolymer of 40-75 % by weight of a vinyl lactam, preferably vinyl pyrrolidone, 15-40 % of a polymerizable carboxylic acid, preferably acrylic acid or methacrylic acid, and 5-25 % of a hydrophobic monomer, preferably a long chain alkyl (C8-C24) acrylate, methacrylate, acrylamide or methacrylamide. The terpolymer has a K-value of 30-55, preferably 40-50, which provides compositions having good sprayability in both pump and aerosol form, and small, fine spray particles.

A gas hydrate inhibitor includes, by weight, a copolymer including about 80 to about 95 % of polyvinyl caprolactam (VCL) and about 5 to about 20% of N,N-dialkylaminoethyl(meth)acrylate or N-(3-dimethylaminopropyl) methacrylamide.
摘要:
This invention relates to laundry detergent compositions, and, more particularly, to such compositions contianing water soluble poly (vinylpyridine) betaine polymers containing a quaternary nitrogen and a carboxylic acid group, which polymers have effective dye complexing properties therein.
摘要:
This invention relates to dye complexing polymers, and, more particularly, to water soluble poly(vinylpyridine betaines) containing a quaternary nitrogen and a carboxylate salt. The polymers herein have effective dye transfer inhibitor (DTI) properties for use, for example, in laundry detergent and fabric softener compositions.
