Patent number: 6897282Abstract: The invention relates to a method of forming a polyphenylene ether resin containing residual aliphatic unsaturation. A polyphenylene ether is reacted with a capping agent in a solvent to form the polyphenylene ether resin containing residual aliphatic unsaturation, which is precipitated from solution by combining the solution with an antisolvent. The precipitated polyphenylene ether resin containing residual aliphatic unsaturation has lower levels of residual impurities than the same compound isolated by devolatilization.Type: GrantFiled: October 3, 2003Date of Patent: May 24, 2005Assignee: General ElectricInventors: Amy Freshour, Hua Guo, Robert L. Howe, Edward N. Peters, Gary William Yeager

Patent number: 6855771Abstract: A process for manufacturing block polymer or copolymer from isotactic polypropylene. Polyolefins are introduced into an extruder. Free radical generator is mixed with the polyolefins to form a mixture at room temperature for free radical formation. The mixture is brought up to a temperature of between 175° C. to 220° C. Chain degradation of the polyolefins is induced by the free radical formation to form degraded polymer. Alkenically unsaturated monomers or polymer segments are mixed with the degraded polymer to form a second mixture. The temperature of the second mixture may be lowered to a temperature of between 90° C. to 150° C. The temperature of the second mixture is then adjusted to a temperature between 100° C. to 250° C. to form a novel block polymer or copolymer.Type: GrantFiled: October 31, 2002Date of Patent: February 15, 2005Inventors: Grant Doney, Keith Salsman
