Patent number: 8378015Abstract: Hot melt adhesive compositions containing hyper-branched SBS block copolymers and end use applications thereof. The hyper-branched SBS is characterized in having a ratio between light-scattering molecular weight (of non-di-block polymer) and GPC molecular weight (of non-di-block polymer) greater than 1.4 and having ratio between light scattering molecular weight molecular weight (of non-di-block polymer) and light scattering molecular weight molecular weight (of di-block polymer) greater than 5. The ratio between light scattering molecular weight MW (of non-di-block polymer) and light scattering molecular weight MW (of di-block polymer) also defines the number of arms for the hyper branched structure. The weight average molecular weight of each arm of the hyper-branched SBS block copolymer is less than about 100,000.Type: GrantFiled: February 15, 2010Date of Patent: February 19, 2013Assignee: Henkel AG & Co.

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
