Proceeds from preparation of POLYMERES thermostables based maleimides dont UN bismaleimide solixane et de diamines aromatiques

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) an N,N'-bis(maleimide) containing a diorganopolysiloxane bridge; (c) a diprimary diamine; optionally, (d) at least one other comonomer copolymerizable therewith; and, optionally, (e) a catalyst therefor.
