Copolymerization of N-vinylformamid and N-vinylcaprolactam

N-vinylformamid is isomer of acrylamide.The latter can be used to replace copolymerization of N-vinylformamid and its copolymer,reducing second environmental pollution.In different molar ratio's condition,N-vinylformamid and acrylamide can carry out copolymerization before the copolymerization of N-vinylcaprolactam and N-vinylformamid continue.A study of the different monomers and different molar ratio's process of copolymerization is conducted.The copolymer compositions are analyzed and the glass transition temperatures of copolymer are determined.
