ICS: C08L033-00; C08G018-32. APPLICATION: EP 84-303409 18 May 1984. PRIORITY: GB 83-17354 27 Jun 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) A polymer-modified polyol, useful in the manuf. of polyurethanes, is prepd. by reacting an org. polyisocyanate with a compd. having a mol. wt. of ￡600 and contg. at least 1 OH group in a polyol which has a mol. wt. of 31000 in the presence of an acrylic pigment dispersant. Thus, 12.54 parts TDI was added to a blend contg. polyethylene-polypropylene glycol triether with glycerol (I) [9082-00-2] (mol. wt. 3500) 80.0, triethanolamine 7.46, and 2-ethylhexyl acrylate-glycidyl methacrylate-hydroxyisopropyl methacrylate-methacrylamide-styrene copolymer p-aminobenzoate [95567-29-6] (dispersant) 1.0 part in the presence of dodecyldimethylamine. A good dispersion of tolylene diisocyanate-triethanolamine-I copolymer [80316-39-8] in I having a viscosity of 30 P was obtained, whereas a polymer-modified polyol made without the dispersant gave a coarse, solid paste.
