Abstract

The effect of polymer structure on blend miscibility with poly(vinylphenol) (PVPh) has been studied for a variety of polyesters that contain aromatic moieties in their backbone. In general, polyesters derived from aliphatic diols showed evidence of interaction and miscibility with PVPh. However, immiscibility was observed if the aromatic content of the polyester was very high. Polyesters derived from aromaticcontaining diols generally showed little interaction and no miscibility with PVPh. Both solution-blending and melt-blending methods were utilized to prepare the blends. Good correlation between the thermal behavior and infrared results was observed. Miscibility of PVPh was observed with polyesters consisting of terephthalic acid and a mixture of ethylene glycol and 1,4-cyclohexanedimethanol moieties for copolymer compositions containing at least 20 mol % ethylene glycol. Miscibility was observed with poly(ethylene terephthalate), poly(butylene terephthalate), poly(2,2-dimethylpropylene terephthalate), poly(ethylene 2,6-naphthalenedicarboxylate), and a copolymer of terephthalic and pentanedioic acids with 1,2-propanediol and glycerol as well as with several cyclic aliphatic copolyesters containing 1,4-cyclohexanedicar boxy lie acid. Miscibility of PVPh was not observed with poly(l,4-cyclohexylene dimethylene terephthalate), Ardel D100, Eastman Kodar copolyester A150, several other polyesters with high aromatic content, and two liquid crystalline polyesters.
