摘要：
An internal mould release composition, suitable for use in the production of moulded articles by the RIM process comprising :
a) a metal salt of an organic acid, said metal salt having mould release properties, and
b) a polymer having a molecular weight of at least 1500 containing at least two guanidine or isourea groups of the formula :
wherein A represents
and wherein each of Q¹ and Q², independently, represents hydrogen, alkyl or cycloalkyl and each of Q³ and Q⁴, independently, represents hydrogen, alkyl, cycloalkyl, arakyl or aryl.
