ABSTRACT:
A method in which a mould is coated with a reactive polymer, a liquid curable composition is filled into the mould and cured under conditions such that the reactive polymer becomes covalently bonded to the cured bulk mould material at the interface. The reactive polymer has zwitterionic groups to confer improved biocompatibility on the moulded product. The reactive group on the reactive polymer is conveniently an ethylenically unsaturated group. The curable composition is suitably a radical polymerisable ethylenically unsaturated monomer mixture or a platinum-curable liquid silicone composition.
