ABSTRACT:
A method for the preparation of a variety of engineering polymers and copolymers, in particular aromatic polymers and copolymers which comprises reacting a stannylated reactant containing a first monomeric or polymeric moiety with an electrophilic reactant, usually a di(acid chloride) containing a second monomeric or polymeric moiety. The intermediate and second compound react by way of a condensation reaction to eliminate the tin and polymerise together the first and second moieties. Some novel polymers and copolymers can be prepared using this method.
