Method for forming bodies comprising previously crosslinked thermally stable resin and product made thereby

摘要

A method of forming a body comprising resin material which can be crosslinked to form a thermally stable resin is carried out by the sequential steps of: (A) providing a body of resin which can be crosslinked to form a thermally stable resin; (B) selectively crosslinking said body to provide a first zone of substantially uncrosslinked resin; a zone of substantially crosslinked resin and a transition zone therebetween; (C) forming said first zone and transition zone; and (D) substantially crosslinking said first zone and transition zone. Step (C) can be carried out by introducing a first zone and associated transition zone into a mold cavity in effective contacting relationship with second zone of substantially uncrosslinked resin and associated transition zone and then step (D) can be carried out to thereby bond said first and second zone together. The present invention also relates to the products made by the method of this invention.
