Abstract
Novel heat-stable imido polymers, well adapted for the production of a wide variety of useful shaped articles, comprise the coplymerizate of (a) at least one diorganopolysiloxylated N,N'-bismaleimide having the following general formula (I): ##STR1## with (b) at least one other N,N'-bismaleimide comonomer, optionally, (c) at least one olefinically unsaturated comonomer copolymerizable with the bismaleimides (a) and (b), and, also optionally, (d) a catalyst.
