Abstract

Quantitative aspects of chain extension of telechelics have been studied. Molecular weight independent characteristic terms were defined and simple expressions were derived for number average extension, {Mathematical expression}, and number average degree of extension, {Mathematical expression}, as a function of number average functionality (-Fn) of telechelic prepolymers. Analysis of these expressions indicate that Ēn and -DEn are enormously sensitive to insignificant changes in -Fn close to ideal -Fn = 2.0. Molecular weight of the extended polymer (-Mr) has also been calculated considering -Fn, number average molecular weight of the prepolymer (-Mn), and molecular weight of the extender (Me).
