Physical Aging near the Beta Transition of a Poly(amide->imide)... [Pg.158]

In the present research, variables associated with physical aging near the alpha transition were used to examine the beta transition of a poly(amide-imide). After sample drying, the relationship between the beta transition s activation enthalpy and thermal history was explored. [Pg.159]

In another development, thermal analysis of POSS-containing ABA triblock methacrylate/butyl acrylate copolymers (Fig. 4) indicated the presence of two clear glass transitions in the microphase-separated system, with strong physical aging observed in samples annealed at temperatures near the Tg of the poly(methacryl-POSS) phase [122].
