| titleOfInvention | Polymer of isocyanate having optically active carbamate group and process for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a novel optically active polymer that can be expected to be used as an optical material. A polymer of an isocyanate having an optically active carbamate group. This polymer includes an isocyanate polymer having an optically active carbamate group mainly composed of a structural unit represented by the following formula (1) and having a degree of polymerization of 5 or more. [Chemical 1] (In the formula, n is an integer of 2 to 8, R 1 , R 2 and R 3 are different from each other and are H or an alkyl group having 1 to 8 carbon atoms.) R 1 is —H, R 2 is —CH 3 , R 3 may be —CH 2 CH 3 . [Selection figure] None |
