Beschreibung
Zusammenfassung:	A sprayable and foamable insulating composition comprising: (A) at least one low molecular weight polymer selected from the group consisting of ethylene/alphaolefin copolymer, ethylene/alphaolefin/nonconjugated polyene terpolymer, polyacrylate, polymethacrylate, polyisoprene, polyacrylonitrile, polymethacrylonitrile and polybutadiene; (B) an effective amount of curative; and (C) an effective amount of a blowing agent having an activation temperature which is less than or about equal to the curing temperature of component (B), said composition having a Brookfield viscosity of about 100,000 centipoise or less at shear rates of 5 sec-1 or greater. A process for providing a layer of insulating foam employing such composition is also disclosed.
