摘要: Switching valves, e.g. for a closed-type molding apparatus for manufacturing polyurethane elastomers and the like, comprising a valve body having a plurality of openings, preferably five, serving as inlet and outlet ports, and a preferably rotatable valve sleeve which serves for switching the openings without any danger of introducing any other material into the switching valve system. Connections are made between pairs of adjacent openings, one of them being cut off from communication.

摘要: Urethane elastomers are prepared by reacting a long-chain polyol having a molecular weight of 400 - 5000 in a one-shot operation with an organic diisocyanate and a halogenated aromatic diamine of the general formula: ##STR1## wherein X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are the same or different and each represents a halogen atom and n is zero or 1. According to this process, urethane elastomers possessing excellent physical characteristics can be produced economically and advantageously in the operations.
