Abstract
Improvements in the processes related to block copolymers and, more particularly in the processes to prepare them, characterized by copolymerizing polyamide and poly (dioxa-amide), acting so that the copolymer has a molecular weight of about 5,000-100,000 and the following formula repetitive structural: ** (See formula) ** in which R1, R2 and R3 are chosen from the group consisting of H, C1-C10 alkyls and C3-C10 isoalkyls, R4 is chosen from the group consisting of C1-C10 alkylene and B3-C10 isoalkylene, R5 is chosen from the group consisting of C0-C10 alkylene and C3-C10 isoalkylene, and y = 2-100 z = 2-150.
