Abstract
Copolymers are produced when a 3,4-epoxy-1-butene monomer is copolymerized with a maleimide monomer in the presence of a free radical initiator. The copolymerization involves both 1,2-propagation and 1,4-propagation of 3,4-epoxy-1-butene. Products of this invention can be cast as clear films and can also be used as reactive polymers.
