ABSTRACT:
Disclosed are cure-to-elastomer compositions comprising: (A) a moderate-to-long chain di or polyfunctional prepolymer having vinyl reactive ends, (B) a cross-link controlling material which is (i) reactive with said moderate-to-long chain di or polyfunctional prepolymer, and (ii) soluble in or miscible with the moderate-to-long chain prepolymer; and (C) a free radical polymerization initiator. The polymerizable compositions of the present invention can be rapidly cured at room or moderate temperature to produce elastomeric materials of high flexibility and appropriate tensile strength.
