POLYURETHANE COMPOUNDS AND ARTICLES PREPARED THEREFROM

This invention relates to polyurethane compounds, e.g., elastomers, which are the reaction product of a cycloaliphatic diisocyanate, a polyol and a chain extender. The cycloaliphatic diisocyanate comprises (i) trans-1,4-bis(isocyanatomethyl)cyclohexane or (ii) an isomeric mixture of two or more of c...

Zusammenfassung:This invention relates to polyurethane compounds, e.g., elastomers, which are the reaction product of a cycloaliphatic diisocyanate, a polyol and a chain extender. The cycloaliphatic diisocyanate comprises (i) trans-1,4-bis(isocyanatomethyl)cyclohexane or (ii) an isomeric mixture of two or more of cis-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, cis-1,4-bis(isocyanatomethyl)cyclohexane and trans-1,4-bis(isocyanatomethyl)cyclohexane, provided the isomeric mixture comprises at least about 5 weight percent of said trans-1,4-bis(isocyanatomethyl)cyclohexane. This invention also relates to shaped and molded articles prepared from said polyurethane compounds.
