ABSTRACT:
Urethane compositions generally free of phase separation patterns and flow lines are produced. One method includes the utilization of a nucleating compound which is generally added to a urethane prepolymer before any chain extension thereof. Examples of nucleating agents include urethanes, ureas and allophanates such as carboxylic acids, organic acid and anhydrides, amides, imides and the like. Another method includes adding a very small initial incremental amount of a curing agent to the prepolymer with an insoluble product being produced thereby and subsequently adding the remainder of the curing agent.
