Description
Summary:A series of new polymerizable oligomers of the general formula , where R = CH 3 , CH 2 Cl, n = 5−40, was synthesized via cationic polymerization of propylene oxide and epichlorohydrin in the presence of tin tetrachloride and methacrylic acid or its anhydride as chain transfer agents. It was shown that the chain length of oligomers is determined by the initial monomer/regulator ratio, a relation that makes it possible to prepare oligomers with the desired molecular mass. The synthesized oligomers readily dissolve in organic solvents and polymerize and copolymerize with unsaturated monomers to give networks or branched polymers.
