Patent number: 8623969Abstract: The present invention is directed to a series of glycerin based polymers that have been designed to have very specific substitution patterns, herein referred to as regiospecific substitution (RSS). The attachment of terminal mono-functional silicone polymers engineered polyesters of glycerin results in heretofore unrecognized products. The unique properties include lower surface tension, better spreadability and a dry skin feel, all of which cannot be attained without the use of a terminal silicone.

Publication number: 20130034609Abstract: The present invention provides a porous hollow silica micro- or nanoparticle with a polymer grafted thereon, wherein the polymer is selected from poly(methacrylic acid) and copolymers thereof. The polymer may be covalently linked to the silica particle via a bridging group. Provided is also a method of covalently coupling a poly(methacrylic acid) to a silica surface of a hollow silica particle. The method comprises contacting a silica surface of a hollow silica particle that carries amino functional or halogen functional groups with a poly(methacrylic acid) or a copolymer or a respective monomer thereof. The method further comprises allowing the carboxyl group of the monomer or the poly(methacrylic acid) and an amino functional group or a halogen functional group on the silica surface to undergo a coupling reaction, thereby covalently coupling the polymer to the silica surface.Type: ApplicationFiled: February 9, 2010Publication date: February 7, 2013Applicant: Agency for Science, Technology and ResearchInventors: Ye Liu, Chee Leng Lay
