摘要：
Styrene was copolymerized with two commercially available ketone functional monomers; i.e., methyl vinyl ketone (MVK) and benzalacetone (BA). BA copolymerizes poorly with styrene. This, along with its low volatility, results in high residual BA monomer in the final polymer. C-13 NMR characterization of SBA showed that the polystyryl radical adds to both carbons of the double bond and at similar rates. The SMVK copolymers were found to degrade twice as efficiently as SBA copolymers.
