- 摘要：
- Prodn. of opt. cellular polyurethanes is by reaction of polyisocyanates with (i) mixts. of (a) fatty acid/basic polyol salts and (b) non-functional fatty acid esters and/or hydrocarbons; and opt. also (ii) cpds. of mol. wt. 62-399 contg. ≥ 2 NCO-reactive H atoms; (iii) cpds. as per (ii) but of mol. wt. 400-10,000; and (iv) known blowing agents, catalysts etc.
