聚氯乙烯-低分子量聚异丁烯共混物的阻尼性质

STUDY ON DAMPING PROPERTY OF POLYVINYLCHLORIDE-POLYISOBUTYLENE OLIGOMER BLEND

聚氯乙烯(PVC)用作阻尼材料时多作成与高聚物的共混物,也有采用IPN的方法改善PVC的阻尼性能,前巳报导PVC-丁腈羟低聚物共混物有较佳的阻尼性质。本工作考察了PVC-PIB(聚异丁烯)组成及添加剂对共混物力学性能和动态力学性质的影响。

The effects of polyisobutylene oligomer (PIB) on the mechanical, dynamic mechanical,damping properties and morphology of the polymer blend based on polyvinylchloride(PVC)-PIBwere studied. The influnces of some additives on the damping property of the blend havebeen examined. The results sbow that petroleum resin is a good additive for PVC-PIB blend,improving the compatibility of the blend.
