METHOD FOR THE PREPARATION OF THERMAL STABILIZED POLYMERS BASED ON MALEIMIDES ONE OF WHICH AND EVENTUALLY A BIS-MALEIMIDO-SILOXANO AND DIAMINO-SILOXANOS

摘要

Novel heat-resistant maleimido polymers, well adopted for the production of molded/laminated shaped articles, are copolymerizates of (a) a hydrocarbyl N,N'-bis(maleimide); (b) a diamine containing a diorganopolysiloxane bridge; optionally, (c) an N,N'-bis(maleimide) containing a diorganopolysiloxane bridge; optionally, (d) at least one other comonomer copolymerizable therewith; and, optionally, (e) a catalyst therefor.
