Calculation of the Glass Transition Temperatures of Linear Polymers. Part 2. The Polymer Data Set

摘要

A large data set of 1179 polymers, with corresponding glass transition temperatures, is tabulated both in the form of chemical structures and in numerical form suitable for computer analysis. Polymers have been analyzed 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 suggested that the polymer data set, with appropriate modifications and improvements, should be used as a standard set for the evaluation of Tg relationships. Great Britain. (JES)
