Abstract
Pelletized thermoplastic polymers or resins containing (--CONH--) groups such as the nylons can readily be brominated or chlorinated in organic solvents to convert the (--NH--) units to (--NBr--) or (--NCl--) units and to form solutions of the N-brominated or N-chlorinated thermoplastic polymers or resins. These N-brominated or N-chlorinated thermoplastic polymer solutions can be coated on a cellular or solid rubbery hydrocarbon polymer substrate, such as an EPDM rubber in the form of a weatherstrip or glass run channel, dried and irradiated with ultraviolet light or heated at a temperature and for a period of time sufficient to reform the amide (--CONH--) groups and to provide the rubbery substrate with an adherent and abrasion resistant coating which also exhibits reduced ice adhesion and coefficient of friction.
