Patent number: 6962965Abstract: A functionalized poly(arylene ether) having a pendant carbon—carbon double bond is prepared by reacting the hydroxy end group of a poly(arylene ether) with a polyisocyanate compound to produce a urethane-capped poly(arylene ether) having pendant isocyanate functionality, which is then reacted with a polyfunctional compound having a carbon—carbon double bond and a hydroxy, thiol, or amino group. The functionalized poly(arylene ether) is useful as a component of a curable composition in which its carbon—carbon double bond copolymerizes with one or more olefinically unsaturated comonomers.Type: GrantFiled: February 20, 2004Date of Patent: November 8, 2005Assignee: General Electric CompanyInventor: Gary William Yeager
