LOW VISCOSITY AROMATIC POLYOLS AND METHODS FOR THEIR PREPARATION |
| 摘要 |
<p>A method for preparing aromatic polyols useful for the production of polyurethane and polyisocyanurate polymers involves digesting scrap polyalkylene terephthalate polymers with a digesting agent, typically a low molecular weight polyol. The digestion product is then treated with an alkylene oxide to produce a low viscosity polyol which displays excellent stability over long term storage.</p> |
