Abstract
Samples of randomly branched poly(butyleneterephthalate) with different degrees of branching were prepared by polycondensation of dimethylterephthalate (DMT), 1,4-butanediol (BD) and small amounts of 1,3,5-trycarboxymethylbenzene (TMT) (from 0.005 to 0.015 (mol TMT)/(mol DMT)).
The values of w were calculated according to Stockmayer from the reaction conversion, p, and correlated with melt-flow index.
Bate's empirical equation provided a good correlation between the branching parameter, w, and the viscosity ratio (<ηb>/<η1>).
