    • 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. The prepolymer is moisture cured to form a silylated MHMS polymer. The process of preparing a MHMS polyol comprises (A) reacting a fatty acid ester wherein at least about 80 weight percent of the fatty acid esters are methyl 9 (10) hydroxymethylstearate, or are prepared from an oil having fatty acids or fatty acid esters which are at least about 80 weight percent oleic acid or esters thereof with an initiator having at least 2 reactive groups selected from primary hydroxyl groups, amine groups, terminal isocyanate groups, terminal carbonyl groups or a combination thereof. The process of preparing at least one MHMS alkoxysilane prepolymer comprises steps of: (a) supplying at least one MHMS polyol; (b) supplying at least one isocyanate functional silane and (c) admixing the MHMS polyol and isocyanate functional silane or combination thereof, optionally in the presence of at least one catalyst to produce at least one MHMS alkoxysilane prepolymer. A process of preparing at least one silylated MHMS polymer comprises steps of: (a) supplying at least one MHMS alkoxysilane prepolymer; and (b) exposing it to moisture under conditions such that at least one silylated MHMS polymer is formed. Articles comprising the polyol, prepolymer, or polymer include elastomers, sealants, adhesives, coatings and the like.
