ABSTRACT:
A solventless prepolymer which is liquid at room temperature and cures at about 350.degree. F. The novel prepolymer is formed from a rubber monomer; acrylonitrile or methacrylonitrile; and an ether derivative of methylol acrylamide. The ether is formed from methylol acrylamide and an alcohol which boils above the cure temperature of the prepolymer and which preferably is hexyl carbitol. The prepolymer is formed with sufficient chain transfer agent to establish a weight average molecular weight of the prepolymer less than about 25,000. The prepolymer is heat curable to form a solid polymer with excellent compression set, tensile strength, and fuel resistivity. The method of formulating these polymers is also disclosed.
