monomers used in photoplastic polymers, have been synthesized from a synchronized, rapid addition of a concentrated mixture of 2 mol equiv alkyl halide and 1 mol equiv 3-mercapto-2-mercaptomethyl-1-propene (A) in MeOH in one syringe and an equi-volume two mol equivalent sodium methoxide in MeOH in another syringe. Thus, two-fold excess 3-chloro-2-chloromethyl-1-propene (B) with A gave B-A-B and B-A-B-A-B
