ON THE APPLICATION OF AN ASSOCIATION MODEL TO BLENDS CONTAINING POLY(HYDROXY ETHER OF BISPHENOL-A)

The possibilities and shortcomings of the Painter-Coleman association model (PCAM) to predict some thermodynamic properties of polymer blend s are explored. More specifically, enthalpies of mixing, excess heat c apacities, melting point depressions in crystalline/amorphous blends, and the evolution of the glass transition temperature with blend compo sition are simulated for blends of phenoxy (a copolymer of Bisphenol A and epichlorohydrin) (PH) with families of polymers, including poly(a lkylene oxides), poly(vinyl alkyl ethers), aliphatic polyesters, and p olymethacrylates. Results are compared with some previously reported e xperimental data.
