    摘要: A polyester polyol, referred to hereinafter as a MHMS polyol comprises fatty acid based mer units wherein at least about 80 weight percent of the fatty acid based mer units are from methyl 9 (10) hydroxymethylstearate, or is prepared from an oil having fatty acids or fatty acid esters which are at least about 80 weight percent oleic acid or esters thereof and which has an average hydroxyl functionality of from 1.5 to 4. A reaction product, referred to herein after as MHMS alkoxysilane prepolymer, is produced from at least one such MHMS polyol and at least one isocyanate functional silane. This prepolymer is moisture cured to form a silylated MHMS polymer.
