Phase Behavior and Miscibility Electronic Database of Binary Polymer Blends Based on Styrene and 2, 6-Dimethyl-1, 4-phenylene Oxide

The purpose of this work is to facilitate modeling and understanding the phase behavior phenomena in homopolymer/homopolymer, homopolymer/copolymer and copolymer/copolymer blends (based on styrene, 2, 6-dimethyl-1, 4-phenylene oxide and their derivatives) by using unpublished experimental data. The present work is a subsidiary contribution to our previous studies1, 2 concerning polymer/polymer miscibility. As it is known, there is an overall paucity of available information on the thermodynamic properties of polymer blends, especially if one of the components is random or alternating copolymer. The data type for different polymer systems varies considerably in quality, quantity and in the nature of experimental information provided, what makes the tabulation of data difficult. For these reasons, a systematic study was done in analyzing all available experimental data and related details concerning miscibility and phase behavior in binary blends of above mentioned systems, and an electronic database was built up. The available experimental data (most of them are from our laboratory) are accounted for on the basis of individual segmental interaction parameters by applying mean-field theory. For each polymer blend, the database contains the following information: component codes or identification numbers ; system type code (homopolymer/homopolymer, homopolymer/copolymer, and copolymer/copolymer) ; composition code for the copolymer constituents ; the blend composition ; a number of data points ; data type code (such as miscibility/immiscibility behavior of the blend at a given temperature) and the miscibility data. In addition, the relevant literature references are included. _____________________________ 1. G.Bogdanić, R.Vuković, F.E.Karasz, W.J.MacKnight, Fluid Phase Equilibria, 139 (1997) 277-294. 2.
