The solution crystallization kinetics and crystal dissolution behavior of three grades of poly (ethylene terephthalate) in N-methyl-2-pyrrolidinone were studied using turbidimetric and calorimetric methods. The influence of concentration on the equilibrium dissolution temperature was described using

## Abstract Poly(ethylene terephthalate) (PET) was blended with two different poly(oxybenzoateβ__p__βtrimethylene terephthalate) copolymers, designated T28 and T64, with the level of copolymer varying from 1 to 15 wt %. All samples were prepared by solution blending in a 60/40 (by weight) phenol/te
Experimental results are reported for the crystallization and sorption kinetics of poly(ethylene terephthalate) in the presence of CO2 at 35 "C and pressures of 40,50, and 60 atm. The results show that the time scale for crystallization is significantly greater than the time scale for CO2 sorption a
