ABSTRACT:
Super-halogenated unsaturated polyesters having average molecular weights of between 300 and 3,000, comprising units derived from at least one .alpha.-epihalohydrin and from maleic anhydride and optionally from another cyclic organic anhydride, possessing a halogen content arising from super-halogenation of between 1 and 35% by weight and the process for their manufacture which is characterized in that maleic anhydride, alone or mixed with another cyclic organic anhydride, is copolymerized with at least one .alpha.-epihalohydrin in molar ratios of epihalohydrin to anhydride(s) of between 1:1 and 2:1, in the presence of a titanium tetrahalide, the halogen being preferably chosen from the group consisting of chlorine and bromine.
