Abstract

1305433 Process and apparatus for preparing polyesters ALLIED CHEMICAL CORP 1 April 1970 [1 April 1969 10 Dec 1969] 15525/70 Heading C3R A high molecular weight linear polyester or copolyester is prepared by (1) forming a flowable uniform dispersion by mixing (a) a mixture comprising one or more aromatic or cycloaliphatic dicarboxylic acids and one or more alkylene diols having 2 to 10 carbon atoms, with (b) a product obtained by partial reaction of a mixture comprising the said dicarboxylic acid(s) and diol(s), in a proportion of at least 10 weight parts of the partial reaction product per total weight part of the dicarboxylic acid(s) and diol(s); (2) feeding the dispersion to a reaction zone; (3) heating the dispersion in the reaction zone so as to effect partial direct esterification; and (4) further esterifying and polymerizing the product of stage (3) until the required molecular weight is attained. In the examples, polyesters are prepared from terephthalic acid and ethylene glycol and from a mixture of 2,6- and 2,7- naphthalene dicarboxylic acids and ethylene glycol.
