ABSTRACT:
A two part RIM nylon-based urethane block polymer consists of an anionic metal salt catalyst in minor proportions and a prepolymer consisting of the reaction product of a diisocyanate with a mixture of a polymeric triamine having primary amine groups and a polyether diol in a large excess of a ring lactam which serves as a reaction diluent. The prepolymer preparation process is characterized by the immediate formation of a visible high molecular weight polymer gel which redissolves with continued agitation. No free or extractable polymers, diols or isocyanate is observed in the polymer product.
