Abstract
Synthesis of N-vinylacetanilide (VA) by the reaction of acetanilide with acetylene, its polymerization and copolymerization are described.
Rate of vinylation was found to be proportional to the first order both for the catalyst concentration and for the acetylene pressure. Maximum yield of VA was always below 50% under the reaction condition studied, presumably because of some side reactions. Non-polar solvents were preferable for the vinylation to polar solvents.
When homopolymerization of VA was carried out with radical initiator, an amorphous polymer was obtained. With typical cationic, anionic or Ziegler type catalysts, however, no polymerization was observed.Monomer reactivity ratios in the copolymerization of VA with St and with MMA have been determined and Q and e values were calculated as follows:_??_.
