|Abstract:||The miscibility of poly(p-vinylphenol) (PVPh) with several poly(dialkyl itaconate)s and poly(methoxy-carbonylmethyl methacrylate) (PMOCMA) was studied by d.s.c. and Fourier transform infra-red (FTi.r.) spectroscopy. Poly(dimethyl itaconate) and a low molecular weight poly(diethyl itaconate) are miscible with four PVPh samples with molecular weights ranging from 1.7 to 30 kg mol-1. A high molecular weight poly(diethyl itaconate) sample is completely miscible with only two PVPh samples with low molecular weights. Poly(di-n-propyl itaconate), poly(di-n-butyl itaconate) and PMOCMA are not completely miscible with PVPh as shown by the presence of two glass transitions in some blends. FTi.r. studies show the existence of hydrogen bonding interactions between PVPh and the carbonyls of -CH2COOR in poly(dialkyl itaconate)s and the carbonyl of -COOCH3 in PMOCMA, but the interactions are weaker than the self-association of PVPh. © 1995.|
