本研究利用三種不同官能基的鏈增長劑,包括,含酸酐官能基的酸酐-苯乙烯寡共聚合物 (SMA)分子量分別為2000 (SMA1000)及分子量3800 (SMA3000)、環氧官能基的商業級鏈延長劑(TOAGOSEI: XG-4030、UG-4070,BASF:adr-4368-cs)以及含diimide官能基的德國萊茵公司鏈延長劑Stabaxol P,在高溫時經由塑譜儀與聚對苯二甲酸乙二酯(PET)混煉反應,藉此改善PET高分子在混煉過程中水解造成分子量下降的問題。本實驗以測定PET在混煉前後的本質黏度以及分析末端羧基濃度來檢測PET分子量隨加工程序的變化情形。PET聚酯尚未混煉的本質黏度為0.6528 (dL/g),未添加鏈增長劑經過五分鐘混煉後為0.4662 (dL/g);當添加鏈增長劑0.5wt%後,以添加SMA3000鏈延長劑的PET分子鏈水解速率最慢,本質黏度為0.5286 (dL/g);其次是添加UG-4070,本質黏度為0.5100 (dL/g)。本文進一步的以此添加此兩種鏈增長劑為主,研究改變其添加比例時,對防止PET分子鏈水解的影響。在混煉時間五分鐘時,觀察到鏈增長劑SMA3000的最佳添加量為2.0wt%,較理論添加量1.93wt%稍微高一點;而UG-4070的最佳添加量為4.6wt%,較理論添加量4.39wt%來的高。此外、並利用端羧基濃度的測定來驗證其反應機構,結果發現添加SMA3000的端羧基濃度隨著添加比例提高而增加;添加UG-4070的端羧基濃度隨著添加比例提高而減少。而當同時混掺這兩種鏈增長劑到PET進行混煉時,在同樣的添加量前提下,改善效果會較單一種鏈增長劑來的好。
Three types of functional groups of the chain-extenders were used in this study, including poly(styrene-co-maleic anhydride) with Mw.2000 (SMA1000) and Mw.3800 (SMA3000), commercialized epoxy groups compounds (TOAGOSEI: XG-4030,UG-4070, BASF: adr-4368-cs) and diimide groups compound (Rhein Chemie: Stabaxol P). The intrinsic viscosity and its carboxyl group content of the PET/chain-extenders blended mixtures were measured to determine the molecular weight during the blended process in brabender at high temperature. The intrinsic viscosity of pristine poly(ethylene terephthalate) (PET) was 0.6528 (dL/g) before the blending, and then down to 0.4662 (dL/g) after 5 minutes of the blended. Among those chain-extenders used, the hydrolysis rate of the PET could be effectively inhibited by SMA3000 (0.5286 dL/g) and UG-4070 (0.5100 dL/g) when 0.5wt% of the chain-extenders was added in the blend. However, the optimal value of the addition for SMA3000 was 2.0wt% which is higher than the theoretical value of the addition (1.93wt%). In addition, the optimal addition value of the UG-4070 was at 4.63wt% which is higher than the theoretical value of the addition (4.39wt%). Furthermore, the reaction mechanism was demonstrated by measuring the carboxyl group content of the blended mixtures. The carboxyl group content of the PET/SMA3000 was increased with the addition of SMA3000. However, the result of the PET/UG-4070 was the opposite with that of PET/SMA3000. The simultaneously added SMA3000 and UG-4070 into PET was better inhibited hydrolysis rate of the PET than that of PET/SMA3000 or PET/UG-4070 added alone.
