Abstract
NEW MATERIAL:Maleimide esters of formula I (R is residue of cyanate consisting of aromatic group or organic group in which two or more aromatic groups are connected with bridges; n is interal number not less than 1).
USE: The homopolymerization or addition-condensation thereof with amines gives heat-resistant polymers having the same level of heat resistance as that of already known and similar polymers and further improved flexibility; varnish or additive therefor. PREPATATION:The addition reaction between an isocyate of formula II, preferably difunctional isocyanate and maleic anhydride is effected in the presence of a catalyst, preferably a tertiary amine, at 130W200, preferably 170W190°C to prepare the objective compound of formula I without condensation reaction.
