Abstract
A process for promoting the adhesion of polyolefins to metals, glass sheets, cement, asbestos or polar polymers (polyamides, polyesters, ethylene-vinyl acetate copolymers, etc.), which consists in modifying the polyolefin by reaction with 0.01%-7% by weight of a compound selected from the group consisting of bis-maleamic acids, bis-fumaramic acids, alkyl esters of said acids in which the alkyl radical has from 1 to 12 carbon atoms, and precursors of said acids or esters, and successively heating at temperature at which the polyolefin is applied to the support to be coated. The main applications concern the lining of pipes or other manufactured metal articles in order to protect them against chemical and atmospheric agents.
