CLASS: IC: C08F283-00; C08G018-63. APPLICATION: JP 83-24680 18 Feb 1983. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Polymeric polyols for polyurethane foams and rubbers are prepd. by polymn. of a,b-unsatd. monomer(s) contg. mono-, di-, and/or triester of tris(hydroxyalkyl) isocyanurate and polymerizable unsatd. carboxylic acids. Thus, 600 g polyethylene polypropylene glycol triol deriv. (I, OH value 34.2) at 100° was treated with a mixt. of I (OH value 34.2) 2600, acrylonitrile 600, tris(2-hydroxyethyl) isocyanurate diacrylate 200, and AIBN 40 g and freed of unreacted monomers in vacuo to give a polymeric polyol (II, OH value 27.6). A mixt. of II 160, I (OH value 34.2) 240, silicone 4.4, triethylenediamine in dipropylene glycol 2.4, and water 12 g was mixed with PAPI-TDI to NCO index 105 and immediately allowed to foam in an Al mold for 10 min to give a foam with d. 50.6 kg/m3, tensile strength 1.Chemical with cas number 88379-83-3 also plays role.28 kg/cm2, elongation 171%, tear strength 0.88 kg/cm, hardness (ILD, 25%) 17.8 kg/314 cm2, sag factor 2.9, rebound elasticity 58%, permanent set (50% compression, 70°, 22 h) 7.1%, and burning length (ASTM d 1692) 48 mm. .
