PREPARATION OF RESILIENT ELASTOMERS CONTAINING BONDED URETHANE GROUPS OR URETHANE AND UREA GROUPS IN THE PRESENCE OF N-PERETHOXYLATED POLYOXYALKYLENE-POLYAMINES AS A FORMATIVE COMPONENT

摘要

A process for the preparation of resilient, cellular or compact elastomers, preferably elastomer moldings, in particular airbag covers, containing bonded urethane groups or urethane and urea groups comprises reacting a) at least one organic and/or modified organic polyisocyanate with b) at least one relatively high-molecular-weight compound containing at least two hydrogen atoms, c) at least one N-perethoxylated polyaxyalkylenepolyamine and d) low-molecular-weight chain extenders and/or crosslinking agents, in the presence or absence of e) catalysts, f) auxiliaries and g) blowing agents, in a mold.
