Abstract
Process for the preparation of new copolyesters derived from 2,2-dialkylhydroacrylic acids, characterized by causing the polymerization of a 2,2-dialkylproplolactone, of the formula ** (see formula) ** Wherein q and q1 are alkyl radicals of up to 6 carbon atoms and which can be linked to form an alicyclic ring, by the product resulting from its reaction with at least one tertiary cyclic amine selected from the following: (1) 1- azopolycycloalkanes with a nitrogen atom and with 6 to 12 carbon atoms in the polycyclic ring system; (2) h-hydrocarbylaziridines; (3) N-hydrocarbylazetidines; and (4) N-hydrocarbyl pyrrolidines, to form a polymer comprising an amino nitrogen in the chain, which is then copolymerized to reach the desired molecular weight.
