Abstract
PURPOSE: To prepare the titled composition giving a urethane sponge having excellent dynamic durability, by adding a foaming and crosslinking agent to a prepolymer obtained by the reaction of a specific polyester diol with diphenylmethane diisocyanate.
CONSTITUTION: The objective composition is obtained by uniformly mixing (A) a prepolymer obtained by the reaction of (a) a polyester prepared by the reaction of (i) a mixture of ethylene glycol and butylene glycol wherein the ratio of the components is 70/30W30/70 with (ii) adipic acid, with (b) 4,4'-diphenylmethane diisocyanate and (B) a foaming and crosslinking agent (pref. composed mainly of water). The foamed product obtained from the objective composition has a density of pref. 0.3W0.9g/cm3. The ratio of the components A and B is pref. selected to give the molar ratio of NCO in the component B to OH in the component A (NCO/OH) of 1.5W4.0
