Using differential scanning calorimetry and synchronous thermal analysis under dynamic conditions, kinetic regularities of copolymerization of α- glycolide and a mixture of α-β-glycolidewith D,L-lactide in the presence of stannous octoate as a catalyst have been investigated. Some thermodynamic and kinetic parameters of cationic copolymerization of monomers have been determined.

Curing kinetics of MEP-15/593 system and MEP-15/593/660 system is studied by means of differential scanning calorimetry (DSC). Curing kinetic parameters are evaluated and the relationship between diluent 660 and the curing properties is investigated. The results show that the diluent 660 can not only reduce viscosity and activation energy, but also improve the degree of cure and conversion ratio.

Abstract In this paper we carried out the crosslinking of the tetraglycidyl-4,4′- diaminodiphenyl methane epoxy resin by using a reactive poly(arylene ether sulphone) as curing agent. Differential scanning calorimetry was used to derive the kinetic parameters of the reactions involved in the cure process and to evaluate the extent of the reaction as a function of time by measuring the total (ΔHr) and the residual heat(ΔHresid) of the resin at different curing times. A comparatively slower reaction was found to take place when the resin was cured with the poly(arylene ether sulphone) that when it was cured with the conventional curing agent 4,4′-diaminodiphenyl sulphone.
