Abstract
Improvements in the methods related to copolymers, and more particularly in the methods for preparing copolymers, characterized by copolymerizing polyamide and alternating poly (dioxa-amide), acting so that the copolymer has a molecular weight of about 5,000-100,000 and the following two components: (a) an alternating component consisting of: **(See formula)** and one of the following: **(See formula)** in which the relative proportions of each one are n = 1-10, m = 1-10, p = 0-10 and at least p or q must be equal to 1 when the other is 0; and 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 C3-C10 isoalkylene; R5 is chosen from the group consisting of C0-C10 alkylene and C3-C10 isoalkylene; R6 and R7 are chosen from the group consisting of C5-C11 alkylene; and (b) a block component consisting of (see graph) and in which the weight ratio of components (a) and (b) is such that a/b = 0.05-1.5.
