| titleOfInvention | Low-temperature liquid urethane prepolymer |
| abstract | An isocyanate-terminated urethane prepolymer prepared by a urethane reaction between (A) a dihydroxypolyol and (B) an isocyanate compound, wherein the dihydroxypolyol is a mixture of (a) a polyether glycol or a polyether ester glycol containing an oxytetramethylene group and having a molecular weight of from 600 to 5,000 and (b) poly(tetramethylene ether/3-methyltetramethylene ether) glycol comprising a structural unit represented by formula (I): -CH2CH2CH2CH2O-(I) and from 5 to 40% by weight of a structural unit represented by formula (II) based on (b) poly(tetramethylene ether/3-methyltetramethylene ether) glycol: <IMAGE> (II) wherein R1 and R2 each represent a hydrogen atom or a methyl group, at least one of them being a methyl group, and having a molecular weight of from 500 to 5,000, with the proportion of (b) based on the total dihydroxypolyol (A) being from 1 to 50% by weight, at a B/A molar ratio of from 1.2 to 2.2. The urethane prepolymer exhibits liquid nature at low temperature of 10 DEG C. or even less and therefore shows improved workability on mixing with a chain extender, a crosslinking agent, an elastomer modifying filler, and so forth. |
