The active energy ray-curable pressure-sensitive adhesive for re-release includes an active energy ray-curable polymer (P), in which the polymer (P) includes one of a polymer obtained by causing a carboxyl group-containing polymer (P3) and an oxazoline group-containing monomer (m3) to react with each other, and a polymer obtained by causing an oxazoline group-containing polymer (P4) and a carboxyl group-containing monomer (m2) to react with each other.Type: ApplicationFiled: July 5, 2011Publication date: January 5, 2012Applicant: NITTO DENKO CORPORATIONInventors: Katsuhiko KAMIYA, Tomokazu TAKAHASHI, Chie KITANO, Mika OKADA, Takeshi MATSUMURA, Shuhei MURATA, Hironao OTAKE, Masatsugu KOSO

Patent number: 8084541Abstract: Provided herein are compositions comprising an ionomer and a polyamine or a tertiary polyamide. The polyamine and the tertiary polyamide have a molecular weight of greater than 500 Da and do not contain an ester moiety or a primary amine moiety. The polyamine comprises at least three moieties that are tertiary amines or hindered secondary amines, and the polyamide comprises tertiary amide moieties and no secondary or primary amide moieties. The compositions may optionally include a filler. Further provided are articles such as golf balls and films containing these compositions.Type: GrantFiled: February 24, 2011Date of Patent: December 27, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Peter A. Morken, Charles John Talkowski

Patent number: 8080605Abstract: Polymer-filler coupling compounds with the formula B-A-Sx—N are claimed. In these compounds, B is an azaheterocyclic oxygen or sulfur containing moiety, or an allyltin moiety; Sx is a polysulfide, where x is between 2 and about 10; A is a linking atom or group that forms a bridge between B and Sx; and N is a blocking group. Sx can be a disulfide. N can be a conventional blocking group or other group such as -A-B. Methods for using the polymer-filler coupling compounds to modify polymers containing unsaturated carbon-carbon bonds and promote filler dispersion are also claimed. Additionally, vulcanizable rubber compositions containing the polymer-filler coupling compounds and methods for making vulcanized rubber compositions using the polymer-filler coupling compounds are also claimed.Type: GrantFiled: December 28, 2006Date of Patent: December 20, 2011Assignee: Bridgestone CorporationInventors: Yasuo Fukushima, William L. Hergenrother, Russell W. Koch
