| abstract | PURPOSE: To obtain the subject new compound capable of providing an optical material and a plastic lens, having a high refractive index and Abbe's number and excellent in heat resistance and mechanical properties. n CONSTITUTION: A compound expressed by formula I (n 1 is 0-3; n 2 is 2-4), e.g. 2,5-diisocyanatomethyltetrahydrothiophene. The compound expressed by formula I (n 1 is 1; n 2 is 2) is obtained by reacting a compound expressed by formula II (X is Cl, Br or I) with a compound expressed by the formula MOCN (M is a metallic element such as Na, K or Ag). n COPYRIGHT: (C)1992,JPO&Japio |
