      PVC：低分子量的易溶于酮類，酯類和氯代烴類等溶劑。高分子量的難溶。聚氯乙烯樹脂經(jīng)加工成型就得到聚氯乙烯塑料。其單體成本低、生產(chǎn)工藝成熟、易加工成型。耐酸堿性、耐磨性、電絕緣性好，不燃燒；但熱穩(wěn)定性和耐光性差。140℃分解放出氯化氫，在加工成型過程中，需加入穩(wěn)定劑。軟化溫度低，限在80℃以下使用。根據(jù)所加增塑劑的多少，可制得軟質塑料和硬質樹脂。軟質塑料可用作電線電纜包皮和其它絕緣材料，可制成透明薄膜，用作雨衣、臺布、農(nóng)用育秧薄膜等；還用來制人造革、泡沫塑料和氯綸纖維。硬質塑料可用于制板材、管道、貯槽、吸收塔等。氯乙烯經(jīng)懸浮法聚合可得粉末狀樹脂，若用乳液法聚合，可得糊狀樹脂。
