Patent number: 8378014Abstract: The polymer composition comprises a polymer and a liquid compound having poor compatibility with the polymer. When the liquid compound is caused to be held in the polymer in a high concentration, a block copolymer having in the molecule a copolymerized polymer block unit having high compatibility with both of the matrix polymer and the liquid compound is incorporated and dispersed. As a result, the block copolymer serves like a surfactant to form an interface and the liquid compound is enclosed inside the interface to thereby form a liquid-in-solid polymer type emulsion.Type: GrantFiled: July 12, 2006Date of Patent: February 19, 2013Assignee: Sanc Salaam CorporationInventors: Yoshikatsu Mizukami, Eiji Akiba
