Production of polyamide macromers carrying at least one unsaturation at each of the two stiffener of the sequence of polyamide, the macromer obtained and its applications

摘要

Production of a polyamide macromer carrying at least two unsaturations, one at each of the two stiffener of the sequence of polyamide: it is to be polymerized a major part of a monomer of polyamide is at least 5atomes of carbon or to heat a major part of an oligomer of polyamide in the presence of a minor part of at least a unsaturated, capable of react with the terminal groups, - nh or and - cooh of the polyamide shape, as well as of a minor part of an auxiliary comprises providing the fixing of the compound unsaturated to the two stiffener of the polyamide chain, the three materials reactant being held in the molten state to a temperature which is greater to that at which the bottom, their combination.
