EVA交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)度測試系(xi)統中交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)度是指EVA分子經過交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)反應達(da)到不(bu)溶(rong)不(bu)熔凝膠固(gu)化的程度。Principle：是將(jiang)EVA樣(yang)品(pin)置于(yu)二甲苯中萃取，未經交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)的EVA全部溶(rong)到二甲苯中，已交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)的EVA不(bu)溶(rong)，通過殘留試樣(yang)量(liang)與試樣(yang)總量(liang)的比值確定(ding)交(jiao)(jiao)(jiao)聯(lian)(lian)(lian)度。
