23 Jul Method for modifying polylactic acid by adopting unsaturated cyclic acid anhydride or unsaturated cyclic acid imide and its application
Abstract
The present invention provides a method for synthesizing polylactic acid high-molecular material modified by adopting unsaturated cyclic acid anhydride or unsaturated cyclic acid imide, and is aimed at making the modified polylactic acid have the remodifiable structure chain, at the same time making it have the more excellent mechanical and biological characteristics as compoared with non-modified polylactic acid, and the obtained modified polylactic acid can be effectively used as bio-degradable polymer in the fields of tissue engineering support, tissue internal fixing material and agriculture and package material.
