Graft copolymers containing nucleic acid bases and L -Α-amino acids

Graft copolymers of nucleic acid bases and L-Α-amino acids on polyethyleneimine were synthesized, and carboxyl derivatives of adenine and thymine were grafted by the p -nitrophenyl ester method onto linear and branched polyethyleneimine. The carboxyl derivatives of nucleic acid bases were also grafted onto the monomeric graft copolymers of L -Α-amino acids on polyethyleneimine; the carboxyl derivatives were obtained by the condensation of polyethyleneimine with L -Α-amino acids with a coupling agent.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38685/1/170170616_ftp.pd
