POLYMER GEL COMPOSITION AND OPTICAL ELEMENT, RESIN COMPOSITION AND OPTICAL FILM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polymer gel composition having excellent mechanical strengths and excellent stability against repeated volume changes, and to provide an optical element using the same. SOLUTION: The polymer gel composition comprising a polymer gel which can absorb or release a liquid by excitation to reversibly change its volume comprises at least two polymers mutually interacting to form a polymer complex and the liquid to be absorbed in or released from the polymer gel and is characterized in that the polymer gel contains fine particles having a volume-average particle diameter of 1 to 100 nm. The optical element is characterized by nipping the polymer gel composition between a pair of substrates. COPYRIGHT: (C)2005,JPO&NCIPI
