摘要:
Mixtures comprising a low molecular weight polyol having a functionality of from 3 to about 8, a liquid modifier compound having a boiling point above 150*C, such as a hydroxyl-containing polyoxyl-alkylene compound having an average molecular weight above about 700, a polyisocyanate and a non-amine-containing catalyst, instantly set, after a brief induction period, to a solid, dense, non-elastomeric polymeric product which can be demolded within a period of from less than about 1 minute to about 5 minutes.

Mixtures comprising a low molecular weight polyol having a functionality of from 3 to about 8, a liquid modifier compound having a boiling point above 150*C, such as linear and cyclic sulfones, a polyisocyanate and a non-amine-containing catalyst, instantly set, after a brief induction period, to a solid, dense, non-elastomeric polymeric product which can be demolded within a period of from less than about 1 minute to about 5 minutes.
摘要:
Saturated polyester compositions stabilized against thermal degradation by the addition of small amount of a synergistic stabilizing combination of a 5 or 6 membered, cyclic organic carbonate and an antioxidant selected from the group consisting of certain alkylated phenols, polyphenols, alkylphosphites, arylphosphites, aromatic amines and aromatic diamines.
