ABSTRACT:
The present invention relates to a method of producing low density polydi resins having high yield strengths and the products thereof. In particular a polydiene resin, such as dihydroxyl terminated 1,2-polybutadiene is reacted at room temperature with an organic chain extender, such as hexamethylene -1,6-diisocyanate, and a graft comonomer such as N-vinyl-2-pyrrolidone in the presence of a peroxide free radical initiator, such as O,O'-bis(t-butyl peroxy) diisopropylbenzene, whereby a elastomeric material having the peroxide and a graft comonomer dispersed therethrough is produced. At a subsequent period of time, the elastomeric material can be exposed to elevated temperatures whereupon the elastomer is cured to a low density resin having a high yield strength.
