ABSTRACT:
A method is provided for making polyamides and silicone polyamide block and graft polymers by heating a mixture of a lactam in the presence of a silicon containing material, such as a silyl lactam, and a mixture of fluoride ion catalyst and a promoter such as an organic isocyanate. The resulting polyamides or silicon polyamide block or graft polymers can be utilized to make silicone elastomeric adhesives or injection moldable polyamides.
