Patent number: 9163102Abstract: Branched polymers are prepared from at least (A) at least one monomer having an electron donor moiety, (B) at least one monomer having an electron acceptor moiety, and (C) at least one multifunctional branching agent comprising a urea moiety and at least two N-vinyl groups. The branched polymers are least 20% (by weight) soluble in a solvent for which the corresponding polymer of equal molecular weight made without said multifunctional branching agent is at least 20% (by weight) soluble. Due in part to the wide range of chemistries and solubility and rheological properties, the branched polymers find application in personal care, pharmaceutical/nutritional, and performance chemicals compositions.Type: GrantFiled: November 30, 2012Date of Patent: October 20, 2015Assignee: ISP INVESTMENTS INC.Inventors: Cristian Grigoras, Krystyna Plochocka, Osama M.

Patent number: 7288597Abstract: What is described is a reactive extrusion process of making a polymeric hydrogel of a polymeric anhydride or acid, e.g. maleic anhydride or maleic acid polymer, or copolymer thereof, crosslinked with a crosslinking agent containing at least 2 crosslinkable groups, particularly, —OH or —NH2, or both. The reaction product is a crosslinked polymeric ester or amide/imide, or both, suitably having a mole ratio of —OH, or —NH2, to —COOH, of 1:10 to 10:1, preferably 2:10 to 7:1. The hydrogel is particularly swellable in water, e.g. >100% in 1 hour in aqueous media; and forms a thin, tacky layer on a substrate, which property is useful in bioadhesive products.Type: GrantFiled: October 10, 2006Date of Patent: October 30, 2007Assignee: ISP Investments Inc.Inventors: Krystyna Plochocka, Timothy G.
