EFFECT OF VARIATION OF BIMOLECULAR RATE CONSTANT WITH CHAIN LENGTH ON STATISTICAL CHARACTER OF CONDENSATION POLYMERS

In this paper we investigate the effect of variation of the bimolecular rate constant with chain length on the statistical character of condensation polymers. The problem in general is too complicated to permit even an approximate solution. Nevertheless, for the case where the rate constant varies linearly with chain length, expressions for the various quantities of interest can be deduced. These results, apart from showing certain quantitative features characteristic of the assumed variation, enable us to draw certain general conclusions. Finally we examine some available experimental data in the light of our theoretical results.
