| Abstract: | In order to synthesize the desired monomer, 1-vinyluracil, a new convenient N-vinylation reaction was first developed as follows. [see PDF for diagram] It was found that using some of the following techniques and combinations thereof, the cyclopolymerization of 1-vinyluracil could be completely repressed. a. polymerization at low temperature b. polymerization at high concentration of monomer c. polymerization in the solid state d. polymerization of negatively charged monomers e. polymerization of monomers containing bulky substituents. ... |
