| 摘要 |
The invention relates to a process for preparing copolymers of p-vinylphenol and allyl esters of ethylenically unsaturated acids which comprises slurrying copolymers of pacetoxystyrene and allyl esters of ethylenically, unsaturated acids in water or an alcohol followed by hydrolyzing the acetoxy groups with an acid or a base with substantially no saponification of the allyl ester groups. The resulting copolymers can be used as vinylphenol copolymers without interfering reactions with carboxylic acid groups since the allyl ester groups are not hydrolyzed. Also, the allyl groups which remain in the copolymers can be used in subsequent reactions, e.g., radiation curing. |
