Abstract

1287781 Polyurethane foams INTER - POLYMER RESEARCH CORP 8 Sept 1969 [11 Oct 1968] 44262/69 Headings C3C C3R and C3T [Also in Division C2] Flexible polyurethane foams having good humid ageing properties are prepared by reacting together a liquid polyester containing from 10 to 72% by weight of the epsilon-oxycaproyl unit [-O(CH 2 ) 5 CO-], at least one organic polyisocyanate, at least one blowing agent, at least one catalyst and at least one surfactant comprising a water-soluble or partially watersoluble polysiloxane-polyester block copolymer. Suitable liquid polyesters are prepared by reacting epsilon-caprolactone, 6-hydroxycaproic acid or an oligomer thereof with a dicarboxylic acid (e.g. adipic, succinic, glutaric, pimelic, azelaic or sebacic acid) or an anhydride thereof, an alkylene glycol (e.g. ethylene, propylene, diethylene, dipropylene, 1,3-butylene or neopentylene glycol) and a triol or tetrol branching agent (e.g. glycerol, 1,2,6-hexanetriol, trimethylolpropane, pentaerythritol or alphamethylglucoside) at temperatures of from 100‹ to 300‹ C. in presence of a polyesterification or ester interchange catalyst. Examples 3 to 10 describe the detailed preparation of suitable liquid polyesters. Suitable polyisocyanates are 2,4- and 2,6-toluene diisocyanates and mixtures thereof, diphenylmethane diisocyanates and mixtures thereof with their corresponding carbodiimide derivatives, and polymeric isocyanates of aniline/formaldehyde or orthotoluidine/formaldehyde condensation products. Suitable blowing agents are water, or mixtures thereof with halogenated aliphatic hydrocarbons or low boiling hydrocarbons. Exemplified catalysts are triethylenediamine, N-ethylmorpholine, N,N - dimethylhexadecylamine and N,N-dimethylbenzylamine. Suitable surfactants are prepared in Examples 12 to 15 and are: (12) a compound of the formula prepared by reacting CH 3 OCO(CH 2 ) 5 OCH 2 CH 2 OCH 2 CH 2 OCH 2 CH 2 OH with a methylhydrogen polysiloxane obtained by cohydrolysis from 8 molar proportions of methyldichlorosilane and 2 molar proportions of trimethylchlorosilane; (13) a compound of the formula prepared by reacting CH 2 : CHCH 2 OCO(CH 2 ) 5 (OCH 2 CH 2 ) 4 O.COCH 3 with a methylhydrogen polysiloxane as in (12); (14) a compound of the formula prepared by reacting a hydroxy-terminated polyester obtained from 1 mol. of 2-ethylhexanol, 5À5 mols. of tetraethylene-oxyglycol and 5À5 mols. of adipic acid, and a methylhydrogen polysiloxane obtained by cohydrolysis of 3 molar proportions of methyldichlorosilane, 15 molar proportions of dimethylchlorosilane and 2 molar proportions of trimethylchlorosilane ; and (15) a compound of the formula prepared by reacting a hydroxy-terminated polyester obtained from 1 mol. of 2-ethylhexanol, 2 mols. of epsilon-caprolactone and 8 mols. of ethylene oxide, and a methylhydrogen polysiloxane obtained by cohydrolysis of 3 molar proportions of methyldichlorosilane, 2 molar proportions of trimethylchlorosilane and 5 molar proportions of dimethylchlorosilane.
