Title: Improvements in or relating to polyurethanes
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G18/10
Filed: 1957-08-02
Abstract: A process of producing a room temperaturestable adduct capable of subsequent conversion into a polyurethane resin product when crosslinked by reaction with a hardener comprises first reacting a long chain polyol with an amount of a bulky aromatic diisocyanate such as naphthalene diisocyanate or p, p1-diisocyanato diphenyl methane sufficient only to produce a first reaction product having end groups of which substantially all are hydroxyl in character and few or none are of isocyanate character, and secondly reacting the first reaction product with an amount of toluylene diisocyanate sufficient for or in excess of that required for providing in a second reaction product constituting the adduct adequate terminal isocyanate groups to render the adduct capable of subsequent cross-linking with polyols, water or diamines.  The term "bulky aromatic diisocyanate" means an aromatic diisocyanate of which the molecular structure includes at least two benzene nuclei or a naphthalene or anthracene nucleus and excludes aliphatic and toluylene diisocyanates.  The term "long chain polyol" means a poly-condensation product of a dicarboxylic acid and a glycol, or a polyether condensate of glycols alone, having a molecular weight of at least 200 and usually in the range 300 to 3000.  In Examples (1) an adduct is produced by reacting an ethylene glycol/adipic acid polyester (M.W.2000) with naphthalene diisocyanate and reacting the product in toluene with toluene diisocyanate.  The product after 6 weeks' storage in an open vessel is converted to a polyurethane film by reaction with N, N, N1, N1-tetrakis (2-hydroxy propyl) ethylene diamine in the presence of acetyl chloride; (2) polyethylene sebacate (M.W.2200), p  p, p1-diisocyanato diphenyl methane and toluylene diisocyanate are employed in a generally similar process.  The adduct can be cured as in Example (1), or with atmospheric water or as described in Specifications 858,096 and 872,569.
