  • Methods for enzymatically preparing polymerizable monomers
    Patent number: 5240835
    Abstract: Unsaturated esters can be converted into unsaturated polymerizable monomers using a biocatalyst derived from Corynebacterium oxydans. The method involves the step of reacting an unsaturated ester with an organic compound having a primary or secondary hydroxy group in a substantially organic environment in the presence of the noted biocatalyst. A transacylase has been isolated from the microorganism and at least partially purified.
