초록

Chlorosulfonated polyethylene(CSM)은 수지의 toughness modifier로서 사용할 수 있다. CSM는 산소와 오존에 대해서 저항성이 클 뿐 아니라 가교 가능한 기능기인 sulfonyl chloride를 가졌기 때문에 금속 산화물에 의해 가교 될 수 있다. Polyvlnylchloride(PVC)는 물성이 좋을 뿐 아니라 값이 싼 plastic이기 때문에 널리 사용되는 범용수지이나 저온에서 충격강도가 약하고 빛과 산소 그리고 오존에 의해서 분해되어 물성을 떨어뜨리는 결점이 있다. 이런 결점을 개선하고저 PVC/CSM 블렌드를 연구하였다. CSM함량 10∼30%에서 현저한 toughening효과를 나타내었다 CSM을 블렌드함으로써 PVC의 내후성, 내오존성 및 기계적 성질이 개선되었으며 toughening효과를 SEM을 통하여 관찰하고 확인하였다.

As a toughness modifier for plastics chlorosulfonated polyethylene(CSM) can be used. CSM has a good resistance to oxygen and ozone. CSM has a crosslinkable functional group(sulfonyl chorlde) with sulfur and metal oxide. Polyvinylchloride(PVC) is widely used industrial plastics because of its balanced properties and low cost. But it has some disadvantages such as low impact strength, light, ozone and oxygen degradation. In order to improve these properties of PVC, CSM was blended with PVC. The toughening effect appeared at about 10wt% and there is no additional effect above 30wt% of CSM. The weatherability, ozone resistance and mechanical properties of PVC were improved by blending with CSM. The toughening mechanism is studied by SEM.
