摘要: The molecular origins of yield and deformation behavior in polycarbonate copolymers were studied with a combination mechanical property, dynamic spectrometry (DMS), solid state variable temperature NMR (VTNMR), Fourier transform infrared (FTIR) measurements. Changes associated physical aging included the study. VTNMR measurements performed using deuterium-tagged PC samples glassy state. As general rule, increased resistance to embrittlement due coincides increasing relative linearity copolymer structure. concepts “short range order” glasses proposed by Haward et al.1 Schaefer al.2 are discussed light results presented here found be partially applicable.
