Publication number: 20030092840Abstract: The present invention includes a composition comprising a coupled impact propylene copolymer. Preferably, the coupled impact propylene copolymer has an elastomeric phase that is present in an amount of at least 9 weight percent of the coupled propylene copolymer. Articles formed from the coupled propylene copolymer exhibit improved directionally balanced impact properties as compared with articles formed form comparable noncoupled impact propylene copolymers and also exhibit improved ductile-to-brittle transition temperatures compared with comparable noncoupled impact propylene copolymers. The invention also includes methods for making the coupled impact propylene copolymers using coupling agents, preferably, poly(sulfonyl azides). The invention further includes articles of manufacture that are made from the coupled impact propylene copolymer of the invention.Type: ApplicationFiled: October 25, 2002Publication date: May 15, 2003Inventors: Patricia Ansems, H.

Compatibilizing agent, radical polymerizable resin composition, molding material, and molded article
Patent number: 6555618Abstract: An object of the present invention is to provide a practical compatibilizing agent which makes it possible to convert the resin mixture into a homogeneous resin mixture free from separation and to eliminate defects caused by separation on molding by prevention of the separation between the radical polymerizable unsaturated resin and low profile additive, which could have not been attained by the prior art.Type: GrantFiled: October 31, 2000Date of Patent: April 29, 2003Assignee: Dainippon Ink and Chemicals, Inc.Inventors: Akira Takano, Takashi Yasumura -
Patent number: 6544653Abstract: An adhesive prepared by blending a hardening resin serving as the main component with an urethane resin having a polycarbonate structure. The addition of the urethane resin with the polycarbonate structure makes it possible to give an adhesive which has a high solvent resistance and a good low temperature impact resistance and achieves good adhesion between vinyl chloride and a steel plate. This urethane resin can be obtained by reacting a polyol with an isocyanate compound. It is advantageous to use the urethane resin in an amount of 5 to 35% by weight.Type: GrantFiled: December 22, 1999Date of Patent: April 8, 2003Assignee: Sony Chemicals Corp.Inventor: Misao Konishi
