Abstract

PURPOSE: To prepare the titled elastomer having excellent physical properties, in high efficiency, by casting and curing a specific isocyanate composition and a curing agent composition containing a polyamine, a polyol and a catalyst using a specific high-pressure mixing process.
CONSTITUTION: (A) A curing agent composition obtained by adding a tert-amine (and a Lewis acid) such as triethylenediamine as a catalyst to an aromatic polyamine[pref. 4,4'-methylenebis(2-chloroaniline), etc.]and an OH-terminated polyol having an average molecular weight of 300W4,000 (e.g. polytetramethyleneglycol having an OH value of 112 and an average molecular weight of 1,000), and (B) a polyisocyanate composition containing isocyanate-terminated prepolymer having an average molecular weight of 500W5,000 and an organic polyisocyanate monomer such as tolylene diioscyanate as essential components, are injected into a mixing chamber at 50W300kg/cm2 pressure, and the obtained mixture is cast in a mold and cured.
