Summary
Binary copolymers of 2- and 3-vinyl thiophene were synthesized via freeradical initiated bulk polymerization. The copolymerizations proceeded readily at 65°C to yield copolymers of reasonable molecular weight. The 2-vinyl thiophene monomer was found to be more reactive than the α-methylene-γ-butyrolactone, while the 3-vinyl thiophene was found to be less reactive than the lactone.
