| titleOfInvention | Polyurethanes derived from modified phenol-aldehyde resins |
| abstract | A process for preparing polyurethanes comprises reacting (1) a product obtained by reacting together (A) a fusible phenol aldehyde resin, and (B) an oxirane ring compound, alkylene halohydrin, alkylene carbonate or mixtures thereof; whereby the phenolic hydroxy groups in the phenol aldehyde resin are etherified with an alkylene-hydroxy group (including a substituted alkylene hydroxy group) with (2) an organic polyisocyanate. A polyether or polyester may be used as a coreactant with compound (1). Many phenols and aldehydes are specified as precursors for compound (A), which may be a resole or novolak. Many oxyalkylating agents, e.g. monoepoxines, glycidyl ethers and diepoxides are specified. Conventional organic polyisocyanates are listed. In Example (29) propylene oxide was reacted with the product of one mole of phenol with 3 moles of HCHO. To the resin thus produced tolylene diisocyanate, Cl3CF, and a silicone oil were added and a foam obtained. In Example (32) the reaction product of phenol, HCHO, triethanolamine and 1:2 propylene oxide was blended with a silicone emulsifier, trimethanol-butanediamine and tolylene diisocyanate and the polyurethane placed between two aluminium sheets. In Example (34) a mixture of (A) the reaction product ethylene oxide with a phenol-formaldehyde resin and (B) the reaction product of trimethylol propane and 1,4,5,6,7,7-hexachlorobicyclo - (2,2,1) - 5 - heptene - 2,3 - dicarboxylic acid was reacted with tolylene diisocyanate in the presence of CCl3F to obtain a polyurethane foam. |
