摘要: In polymer blends where the glass transition temperatures of two components differ greatly, segmental α-relaxation and chain dynamics faster component exhibit a number anomalous properties not seen before in homopolymers, explainable by conventional theory dynamics. first part this paper, these are collected altogether made known. We show their interconnections emphasize necessity explaining all them together if objective is to fully solve problem. second part, predictions from single theoretical framework, namely, coupling model, applied explain toto.
