These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.Type: GrantFiled: May 22, 2008Date of Patent: October 25, 2011Assignee: Lubrizol Advanced Materials, Inc.Inventors: Krishnan Tamareselvy, Thomas A. Barker, James E. Mullee, Charles T. Greenslade, Julie F. Schmucker-Castner, Deborah S. Filla

Patent number: 8030413Abstract: Synthesis methods for creating polymeric compounds comprising dihydroxyphenyl derivatives (DHPD), or DHPp i.e. polymers modified with DHPD, with desired surface active effects are described. The polymer backbone of DHPp has structural or performance features that can be tailored to control physical properties of DHPp, allowing it to be useful for different applications i.e. tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.Type: GrantFiled: November 23, 2009Date of Patent: October 4, 2011Assignee: KNC Ner Acquisition Sub, Inc.Inventor: Bruce P.

Patent number: RE45219Abstract: Provided are a photoreactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.Type: GrantFiled: September 14, 2012Date of Patent: October 28, 2014Assignee: LG Chem, Ltd.Inventors: Heon Kim, Sung Ho Chun, Keon Woo Lee, Sung Joon Oh, Kyungjun Kim, Jungho Jo, Byung Hyun Lee, Min Young Lim, Hye Won Jeong
