Exxon Mobil(以商標名 EXCEED)及 Dow Chemical(以商 標名’’AFFINITY”)製得。相較於以齊格勒-納塔觸媒製 得的LLDPE,mLLDPE具有較窄的分子量分布及均勻 的組成分布。mLLDPE之熔點對於其組成展現顯著的趨 25向,且可極廣泛地改變;例如自i20°C(就含1 1/2莫耳 1299371 A7 B7 五、發明說明(6) 10 15 I_τ 經濟部智慧財產局員工消費合作社印製 20 25 %α-烯烴之共聚合物而言)至11〇〇c(就含3·5莫耳%.烯 fe之共聚合物而言)。相較之下,LLDPE樹脂具有不均 句的組成分布。熔化此等混合物主要憑靠低分支部分 (相當具結晶性)。因此,LLDPE樹脂之低熔點對於共聚 合物組成物不敏感,且通常落於125至128 °C間。 適用於本發明之黏合促進劑可為以馬來酸或馬來酸 酐(ΜΑΗ)接枝之聚稀經,兩者係當接枝至聚婦烴時轉化 為琥珀酸、琥珀酸酐。較佳之合併的ΜΑΗ接枝含量為 1〇重量%(藉滴定測得)。再者,乙烯_丙烯酸系共聚合 物及此等共聚合物與所述接枝聚烯烴之組合係為適合的 黏合促進劑。市售的馬來酸酐接枝之聚乙烯已知為 ASPUN樹脂(自Dow Chemical)。市售的乙稀_丙婦酸系 共聚合物為 Bynel 2022、Bynel 21E533 及 Fiisabond MC 190D或Fusabcmd C(皆得自DuPont)及Ese〇r酸三元聚 合物(自ExxonMobil)。以基礎聚烯烴重為基準,乙烯_ 丙烯酸系共聚合物佔約i至約2〇重量%,較佳佔5至 15重量/。。接枝聚締煙黏合促進劑之含量係使得合併 的馬來酸或馬來酸酐佔約〇 〇5%至約2重量%,較佳佔 〇·1 至 1·5% 〇 增強劑可包含二氧化鈦、滑石、二氧化矽、明礬、 碳酸鈣、氧化鈣、鎂及其他氧化物中之任一種;二氧化 鈦為較佳。以基礎聚烯烴重為基準,於聚合物中使用之 增強劑含量為、約0.1至約1%。為了獲致聚合物中之良 好分散性及良好的可紡絲性,粒度係於約〇 〇4至約5 微米之範圍内,且較佳於〇·〇5至約2微来之範圍内。 裝 訂 [299371
