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.

A method of preparing a block copolymer having blocks of the formula [Figure] comprising reacting a first polymer block (R′)bM-Y-P-Y-M(R′)b where each M is independently tin, germanium, lead, or thallium; each R′is independently a substituted or unsubstituted alkyl or aryl group; each Y is independe
A method of preparing a block copolymer having blocks of the formula [Figure] comprising reacting a first polymer block (R′)bM-Y-P-Y-M(R′)b where each M is independently tin, germanium, lead, or thallium; each R′is independently a substituted or unsubstituted alkyl or aryl group; each Y is independently oxygen, sulfur, or substituted nitrogen or phosphorus; each b is an integer one less than the valence of the element M to which it pertains; P is a divalent polyolefin, polyester, polyamide, polyphenylene ether ketone, polyalkylene ether ketone, polytetrahydrofurane, polydimethylsiloxane, polymethylphenylsiloxane, polyphenylene ether sulfone, polyalkylene ether sulfone, polycarbonate, or polyurethane polymeric group; with a second polymer block [Figure] where each X is independently halide, imidazole, RO-, RS-, or a group capable of reacting with the first reactant to eliminate a by-product containing M and X, R being a substituted or unsubstituted aromatic or aliphatic group or hydrogen; each B is independently carbon, phosphorus, sulfur, silicon, or a direct bond; each Z is independently oxygen, sulfur, or an imino group; each D is independently an aromatic, aliphatic, RO-, RS-, or R2N-group if B is phosphorus and an aryl, alkyl, or RO-group if B is silicon; each d is independently 1 if B is carbon; 0 or 1 if B is phosphorus; 0, 1 or 2 if B is sulfur; and 0 if B is silicon or a direct bond; each e is independently 0 if B is carbon, sulfur, or a direct bond; 1 if B is phosphorus; and 2 if B is silicon; and Q is a divalent polyester, polyamide, polyphenylene ether ketone, polyphenylene ether sulfone, polycarbonate, polydimethylsiloxane, or polymethylphenylsiloxane polymeric group.
