Abstract
Prepn. of polyurethanes by reaction of (A) a polyol contg. 2-8 OH gps. and with OH equiv. 250 max., with (B) an organic polyisocyanate, in the presence of (C) a modifying agent consisting of an oligomer from >=1 monomers with C=C bonds, in th form of a liquid or grease with solubility parameter 8 (Cal/ml)1/2 min. at 25 degrees C and specific heat 0.35 cals./g/degrees C min., and (D) an amine-free catalyst. Used for catng of non-porous, non-elastomeric and quick-setting products e.g. bearing surfaces, spacer rings, toys, decorative articles, furniture components, electrical insulators, wire supports, gears, threaded stoppers, etc. Use of modifier (C) allows thicker parts to be made without cracking and gives higher heat stability than usual modifiers, e.g. dibutyl phthalate.
