什(shen)么是"晶(jing)點"?
晶(jing)點(dian)(dian)(dian)實際上是"過度(du)聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)".即晶(jing)點(dian)(dian)(dian)部(bu)位聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)的(de)分子量(liang)(liang),高于周(zhou)圍(wei)同(tong)種聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)的(de)分子量(liang)(liang),由于分子量(liang)(liang)高,因(yin)此(ci)晶(jing)點(dian)(dian)(dian)部(bu)位聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)具有(you)較高熔(rong)(rong)點(dian)(dian)(dian),在(zai)熔(rong)(rong)化時,熔(rong)(rong)體(ti)具有(you)較高的(de)粘度(du),晶(jing)點(dian)(dian)(dian)部(bu)位聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)在(zai)吹成(cheng)(cheng)薄(bo)膜時,不能與(yu)周(zhou)圍(wei)的(de)同(tong)種聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)相(xiang)互均勻地分散/混(hun)和,并在(zai)熔(rong)(rong)體(ti)吹成(cheng)(cheng)薄(bo)膜后(hou),先于周(zhou)圍(wei)的(de)同(tong)種聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)凝(ning)固(gu).因(yin)此(ci),研成(cheng)(cheng)"箭頭"狀或球狀過度(du)聚(ju)(ju)(ju)(ju)(ju)合(he)(he)物(wu)的(de)凝(ning)固(gu)體(ti).習(xi)慣上被稱為"晶(jing)點(dian)(dian)(dian)"。
