SULFONATED AROMATIC POLYESTER POLYOL CMPOSITIONS

摘要

Aromatic polyester polyols comprising the inter-esterification product of at least one phthalic acid based material, at least one hydroxylated material having a functionality of at least 2, and at least one low molecular weight sulfonated compound, are provided. These polyols may optionally include at least one hydrophobic material as an inter-esterification reactant. Also provided are methods for preparing such polyols. Further described are polyol-based compositions prepared using such polyols and a blowing agent, as well as methods for preparing such polyol-based compositions. Polyisocyanurate and polyurethane foams made from such polyol-based compositions, and to methods for preparing such polyisocyanurate and polyurethane foams are also described.
