  • Method for preparing para-(2-hydroxyalkyloxy) styrene monomers and oligomers
    Publication number: 20050234266
    Abstract: A method for preparing p-(2-hydroxyalkyloxy)styrene monomers and oligomers is described. The method comprises a base-catalyzed reaction of a styrene ester, a suitable alcohol and an alkylene oxide in a single vessel reaction. In this method, the reactive p-hydroxystyrene is generated in situ via the base-catalyzed transesterification reaction between the styrene ester and the alcohol in the presence of the base catalyst. The p-hydroxystyrene formed reacts with the alkylene oxide to form the p-(2-hydroxyalkyloxy)styrene monomer or oligomer.

  • Method for preparing hydroxystyrenes and acetylated derivatives thereof
    Publication number: 20050228191
    Abstract: A method is provided for the thermal decarboxylation of a phenolic substrate in the presence of a non-amine basic catalyst to produce a vinyl monomer. The product of the decarboxylation reaction may additionally be acetylated in the presence of an acetylating agent in the same reaction vessel.
