PHOTO AND BIODEGRADABLE POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a photo and biodegradable polymer composition in which titanium oxide particles is uniformly dispersed without being mutually agglomerated and which keeps inherent transparency of the polymer. SOLUTION: Titanium dioxide whose surface is modified with a or with both saturated or an unsaturated carboxylic acid and a saturated or unsaturated amine. An electron donative group-containing polymer is used as a part of the structure of the polymer so that titanium dioxide in the polymer can be compounded in a nanosize area and the transparency of the polymer composition is kept.
