摘要
本文讨论了聚乙烯动态力学α、β、γ转化的特点和归属。
The morphological origins and molecular motional modes of the dynamic mechanical α, β and γ relaxation of polyethylene have been reviewed with 21 references. The α-relaxation is representative of the motion of the chain in the amorphous phase originating from some type of motion in the crystals. The β-relaxation is analogous to the glass transition. The γ-relaxation is origin of the motion of a short segment -(CH2)n(n≥3)in the amorphous phase.
