Patent ID: 7144979

Claim:
A method for generating a hybrid polymer having first and second and optionally further polymers, said method comprising subjecting said first polymer or a sub-surface region thereof to sufficient physical stress means selected from the group consisting of one or more of stretching, twisting, cutting , scratching, indenting, bending, compressing, heating, flaming, and ejection from a mould, to enable said first polymer or its regions to be capable of acting as a substrate polymer for the grafting of said same and/or one or more other polymers or monomeric precursor forms thereof under radical conditions, contacting the treated first polymer with the second and optionally further polymers or monomeric precursor forms thereof, and subjecting same to conditions sufficient for the second and optionally further polymers or monomeric precursor forms thereof to graft to said first polymer or regions thereof under radical conditions.
