Glass transition temperatures of butyl acrylate-methyl methacrylate copolymers

M. Fern�ndez-Garc�a, Rocío Cuervo‐Rodríguez, Enrique López Madruga

Abstract

The glass transition temperatures Tg of butyl acrylate–methyl methacrylate copolymers obtained by free radical polymerization in 3 and 5 mol/L benzene solution have been measured using differential scanning calorimetry (DSC) and the values have been correlated using Johnston's equation with inter-intramolecular copolymer structure. From the data calculated with copolymer prepared at low conversion, the variation of glass transition temperature with copolymer conversion has been theoretically predicted. © 1999 John Wiley & Sons, Inc.
