✦ Synopsis

It should also be noted that the equation quoted by Williams(l) can be applied only to isothermal work since the introduction of an activation energy implies that the equation has been derived by integrating a rate equation and this integration must have been carried out on the assumption that T is constant.

Various workers (e.g. Johnson and MehIt@, Avrami('), Cook and Richard@))

have developed different rate equations for recrystallization. However, provided

## Abstract This article concerns the __in situ__ compatibilization of immiscible isotatic polypropylene/styrene–butadiene–styrene triblock copolymer blends (i‐PP/SBS) by use of a reactive mixture. For this purpose, maleated PP (PP–MAH) and SBS (SBS–MAH) were used as functionalized polymers and 4,4

The synthesis of thermoplastic polyurethane elastomers (TPUs) is generally carried out using the prepolymer method. To study the influence that the properties of the prepolymer may have in the final TPUs, four TPUs were prepared by using different NCO/OH ratios. The prepolymers and the macroglycol u
