摘要： The present invention is directed to a RIM process utilizing amine chain-extenders and amines of the formula:
where
R₁ is an n-valent group obtained by the removal of hydroxyl groups from an n-hydroxy group containing polyhydroxyl compound having a molecular weight of from about 400 to about 12,000,
R₂ represents hydrogen or an inert substituent,
y is 1 or 2, and
n represents an integer from 2 to 8.
Systems of improved flow are obtained.
