ABSTRACT:
Abstract not available for EP0009613
Abstract of corresponding document: US4343339
The instant invention is directed to a process for the production of
vulcanized elastomers containing urethane groups by casting,
comprising: (A) mixing the following components: (1) liquid diene
polymers containing isocyanate reactive functional groups, (2)
compounds having molecular weights of from 400 to 10,000, and
containing at least two hydroxyl groups, (3) polyisocyanates, (4)
cross-linking agents having molecular weights of from 32 to 400 and
containing at least two active hydrogen atoms, (5) vulcanization agents
used for vulcanization and optionally (6) reinforcing fillers; and
subsequently (B) pouring the mixture into a mold and allowing the
mixture to react in the mold; and subsequently (C) vulcanizing the
molded product at temperatures above 120 DEG C.
