<p>The invention discloses a method and composition for curing TDI-terminated polyether polyol prepolymers with a curative comprising a dihydroxy substituted alkyl or aryl tertiary amine such as phenyldiethanolamine and, optionally, various short-chain diol and/or triol components. The resulting polyurethane elastomers have both low hardness, ranging from Shore A Durometer values of about 20 to about 60, as well as high (greater than or equal to 30) trouser tear values.</p> |
