CALCULATION OF THE GLASS TRANSITION TEMPERATURES OF LINEAR POLYMERS PART 2: THE POLYMER DATA SET

SIMMARY A large data set of 117S polymers, with corresponding glass transition tempera-tures, is tabulated both in the form of chemical structures and in numerical form suitable for computer analysis. Polymers have been analysed into groups with invariant nearest neighbours and where a particular group is found in only one polymer, it has been identified. An unambiguous and easily assimilated method of analysing and classifying polymer structures into combinations of groups is illustrated which could be more widely adopted with much advantage. It is sugges-ted that the polymer data set, with appropriate modifications and improvements
