Abstract

The mechanical, electrical, and thermal properties of polyamide-modified poly (vinyl chloride) (PVC)-sol was investigated. PVC-sol was plasticized with dioctyl phthalate (DOP). In this work, the effects of the addition of polyamide on the properties of PVC-sol seal-ants were investigated. Two kinds of polyamide resins having different amine value were used. It was found that the properties of the PVC-sol sealants were significantly affected by the contents and types of the added polyamide rosins. The PVC-sol sealants modified with polyamide A (low amino value) showed higher tensile properties than those modified with polyamide B(high amino value) did, and thermal stability of the sealants showed nearly the same trends. The tensile strength of sealants were decreased with increasing the $CaCO_3$ contents. The dielectric constant were not strongly dependent on the polyamide types and contents.
