Hexamethylene dichloride

The material obtained from two such runs is combined and fractionated through a Fenske-Whitmore column packed with glass helices. Distillation is carried out at a pressure of 8-12 mm., with a reflux ratio of 5 1. After a fore-run of 5-15 g., about 45 g. (16%) of hexamethylene dichloride distils at 80-84°/9 mm., d 1.4585-1.4565. An intermediate fraction of 10-20 g. distils at...

The first industrial success in step polymerisation was the synthesis and development by Carothers and co-workers at DuPont of the famous polyamide Nylon 6-6, starting from hexamethylene diamine and adipic acid dichloride. As shown in Equation 3.1, this reaction is favoured by elimination of hydrochloric acid. 

TEG, or PEG-2000. These spirocycles were used as initiators for the ring-expansion polymerization of Z-lactide in chlorobenzene at 120 °C. The resulting cyclic block co-polymers were reacted in situ with aliphatic dicarboxylic acid dichlorides (ADADs) or with hexamethylene diisocyanate (HMDI) to achieve chain extension. 

Place about 50 ml of the solution of the appropriate diacid dichloride (in CCI4) in a 100-ml tail-form beaker. Carefully pour about 25 ml of the aqueous solution of hexamethylene diamine along the sides of tlic beaker so that it forms a separate layer over the heavier CCI4 solution layer. When the polymer film appears at tlie interface, hold it gently at its centre with a pair of forceps and lift out of the beaker.
