ABSTRACT

The effect of heating polyhexamethyleneadipamide in an inert medium on its molecular weight was investigated, and it was shown that, irrespective of the initial degree of polymerization, a definite value of the molecular weight is established in the fused polyamide, this value being dependent on the temperature at which the polyamide is heated.The nature of the end groups of the polyamide does not appear to affect the establishment of the equilibrium molecular weight during heating in an inert medium.Emphasis is placed on the part played by degradation-recombination equilibria, in particular by interchain exchange reactions, in the establishment of the equilibrium value of the molecular weight of the polyamide under the conditions indicated.
