- 英文摘要:
The change of molecular weight distribution of PVC by thermal, γ-irradiation
and accelerated weathering were determined by GPC. The chain scission and
cross-linking of the polymer were examined on the change of the normalized
chromatograms. The results are similar to previous findings that all three kinds of
degradation induced the chain scission and cross--linking in thermal degradation. A
reaction mechanism is proposed to explain the different behavior in chain scission and
cross-linking between the three types of degration. - 中文關鍵字: --
