摘要:
Thermally stable block copolymers, well adapted for the production of coating films, include recurring imide/amide blocks of the formula: ##STR1## and recurring urea/siloxane blocks of the formula:--NH--CO--NH--A--NH--CO--NH-- (II)wherein A is a divalent diorganosiloxane radical of the formula ##STR2##
