Polyurethane elastomers from HDI prepolymers with reduced content of free HDI monomers |
摘要 |
Polyurethane prepolymers with reduced amount of unreacted monomeric hexamethylene 1,6-diisocyanate (HDI) are provided. Also provided are polyurethane elastomers obtained by mixing the polyurethane prepolymers having reduced amount of unreacted monomeric HDI with amine and/or hydroxy chain extenders and durable, resilient, colorfast golf ball covers obtained therefrom. Rolls, wheels and tires obtained from the polyurethane elastomers are also provided.
