The reaction produces of (A) polyoxytetramethylene diols or polycaprolactone polyols, (B) diisocyanates and (C) di- or tri-methylol carboxylic acids are capped with (D) certain defined acrylyl compounds to produce terminally unsaturated oligomers that readily cure by thermal or radiation means to soft, tack-free products. The oligomers can be used as coatings; binders and adhesives. |
