MANUFACTURING METHOD OF POLYSILANE OPTICAL ACTIVITY REVERSE THIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a simple manufacturing method of an industrially useful light polarizing film, which can manufacture a film having a light polarizing function only by forming a film by spin coating the solution of the polysilane expressed by formula 1. SOLUTION: The surface of an optically isotropic transparent substrate spun-coated with a uniform solution of polysilane polymer of 10-100,000 in polimerization n in formula 1 or polysilane random copolymer. In the formula, R1-R4are the alkyl groups which may have asymmetric carbon of the carbon number 22 replaced at least to para (p-) or meta (m-), and these can be all the same or different one another, and m is 0 or larger but 1 or smaller.
