聚乙烯醇肉桂酸酯光刻胶的合成

Synthesis of Polyvinylcinnamate for Photoetching Glue

采用新的分级方法,提高了聚乙烯醇的聚合度,缩小了分子量分布范围,使合成的产品性能有较大的提高.

The degree of polymerization and the distribution of molecular weight of polyvinyl alcohol have been increased and narrowed through a new gradation method,and it improves quite a lot the properties of the title product.
