범용성 phthalate계 가소제인 di-2-ethylhexyl phthalate(DOP), diisononyl phthalate(DINP), diisodecyl phthalate(DIDP)에 내한성 2차 가소제인 di-2-ethylhexyl adipate(DOA), diisononyl adipate (DINA)를 첨가하여 PVC sheet를 제작하고 가소화된 PVC의 기계적인 물성, 이행성과 추출성, 저온 유연성 등을 측정하였다. 측정된 물성들을 가소제의 분자구조, 비극성도, 상용성 등의 측면에서 고찰하였다. 가소화 효율이 좋은 내한성 2차 가소제가 첨가됨으로써 변화되는 물성을 관찰하였고 DINP/DOA의 혼합비가 40/10 phr 일 때 기계적 물성이 양호한 상태에서 저온특성이 향상되었음을 알 수 있었다.

Natural rubber (cis-1,4-polyisoprene, NR), polystyrene(PS)에서의 migration은 phthalate계 가소제를 단독으로 첨가했을 때보다는 혼합 가소제를 첨가했을 때 더욱 증가하였으며, phthalate계 adipate계 모두 상용성보다는 분자량이 migration과 더욱 밀접한 관계를 가졌다.

After cold resistant plasticizers(DOA, DINA) was added to primary plasticizers(DOP, DINP, DIDP), PVC sheet was made with this plasticizer-mixtures and PVC. To study the properties of this PVC sheet, mechanical properties, extraction, migration and low temperature flexibility was examined and these properties were explained by the molecular structure, nonpolarity, compatibility and other factors.
By the addition of secondary plasticizers having a good plasticizing efficiency, several variations of properties was observed. When blend ratio of DINA and DOA was 40/10 phr, mechanical properties were preserved in good conditions and low temperature flexibility was improved. Migration to NR, PS was increased when compared with the PVC sheet with primary plasticizer only. In both primary phthalate plasticizers and secondary adipate plasticizers, migration was influenced more by molecular weight than by compatibility.
