Title: Improvements in or relating to high molecular weight polymers
IPC: C08G18/76
Filed: 1958-05-08
Abstract: In a process for the preparation of a polyurethane of high molecular weight an aromatic diisocyanate and ethylene glycol are reacted in an organic solvent medium comprising dimethyl sulphoxide as a major or as the sole constituent.  The process is usually carried out with an aromatic diisocyanate having the formula: <FORM:0867882/IV (a)/1> where Z is the divalent radical -CH2- or -C(CH3)2-.  The solvent medium may also comprise a minor proportion of halogenated lower aliphatic hydrocarbons or ketones which are neutral, non-reactive with the diisocyanate and completely miscible with dimethyl sulphoxide and which have a boiling point below 150 DEG C. such as 4-methylpentanone-2, acetone, methyl ethyl ketone, methylene bromide, chlorobromomethane, chlorobromoethanes, ethylene chloride, trichlorethane and carbon tetrachloride.  Reaction at temperatures between about 50 DEG  and 150 DEG C. gives products having a melting point between about 200 DEG  and 250 DEG C. and an inherent viscosity in N, N-dimethyl formamide at 20 DEG C. of between about 0,4 and about 1,4.  The reaction produces a solution of the polyurethane which can be shaped into fibres, films or filaments.  In typical Examples (1) bis (4-isocyanatophenyl) methane and ethylene glycol are reacted in a mixture of dimethyl sulphoxide and 4-methyl pentanone-2 to give a solution of a product having inherent viscosity 1,38.  The solution is dry spun through a 5 x 0,004 inch hole spinneret and the fibres are drawn through a steam tube to 3,3 times their original length; (4) similar reaction and fibre formation are carried out with ethylene glycol and 2, 2-bis (4-isocyanatophenyl) propane; (5) in a process similar to (1) the dimethylsulphoxide is used mixed with carbon tetrachloride, the solution of the product is extruded into water and the filaments obtained are drawn to twice their original length in hot water.
