Product 1

HCID 8441Dimethyl terephthalate

Procedure

A polyester is produced from 364 g of dimethyl terephthalate, 112 of ethylene glycol and 75 of glycerin and further worked up as described in Example 1, with the exception that instead of 137 g of the diimidodicarboxylic acid (of Example A) there is used 156 g of the reaction product of Example F. The obtained lacquer has a solid body content of 26% and a viscosity of 130 seconds and is used for the lacquering of wire as described in Example 1.
