摘要:

以聚醚四元 (PETO)和马来酸 (MAH)为始物,对甲苯 酸为 化剂,对苯二酚为聚剂,制备了含β反应型流滴剂(βS);研究了反应物、比、 化剂加入量和反应时间间对 化率 影 ;用红外光谱(FTIR)、核磁共振氢谱(H1-NMR)对βS 结构进行了表征;过测定反应后体系中 MAH 残留量,计 了目标产物 化率。结果发现:用该方法测定,反应,化率达95%以上,并且产物收率达到90%以上。将 βS与线形低密度聚乙烯(PE- LLD) 进行反应接枝(PE-LLD-g-βS)后吹 ,发现在60 ℃加 流滴条件下,PE-LLD-g-βS流滴期为76 d, 而普 流滴 为17d。

Abstract: Reactive type dropping agent containing β double bond(βS) was synthesized. Polyether tetrols(PETO)and maleic anhydride(MAH) were used as sta art materials, p-toluene sulfonic acid as catalyst and hydroquinone as inhibitor. The effects of monomer ratio, amount of catalyst and reaction time on conversion were studied. FTIR and H1-NMR were used to confirm the chemical structure of βS. The conversion of the products was calculated based on the resicdual fraction of MAH. The conversion of the reaction was higher than 95 %, and yield higher than 90 %. The films of PE-LLD-g-βS were pre- pared. The dripping durability of PE-LLD-g-βS film and common dripping film at 60 ℃ were 76 days and 17 days, respectively.

Key words: reactive type;dropping agent, grafting, polyethylene, film, dripping durability
