|Abstract:||The miscibility of poly(acetonyl methacrylate) (PACMA) with poly(styrene-co-acrylonitrile) (SAN) and poly(p-methylstyrene-co-acrylonitrile) (pMSAN) has been studied by differential scanning calorimetry. PACMA is miscible with SAN having acrylonitrile (AN) contents between 33 wt% and 58 wt% and with pMSAN having AN contents between 43 wt% and 61 wt%. Three segmental interaction parameters, χ ACMA S, χ ACMA pMS and χ ACMA AN, were found to be 0.15, 0.22 and 0.24, respectively. The results obtained for PACMA are compared to those of poly(n-propyl methacrylate) and poly(isopropyl methacrylate). The miscibility behaviour is discussed in terms of the binary interaction model as well as the non-hydrogen-bonded solubility parameter concept. © 1992.|
