Abstract：
Nowadays, few investigations on the process parameters of grafted starch synthesized using electron transfer atom transfer radical polymerization (ARGET ATRP) and its applications in warp sizing and paper-making are presented. Therefore, this study aimed to survey the appropriate process parameters of bromoisobutyryl esterified starch-g-poly(acrylic acid) (BBES-g-PAA) synthesized by the ARGET ATRP, and also aimed to provide a new biobased BBES-g-PAA adhesive. The appropriate synthesis process parameters were 1.2, 0.32, and 0.6 in the molar ratios of vitamin C, CuBr2, and pentamethyldivinyltriamine to BBES, respectively, at 40 °C for 5 h. The BBES-g-PAA samples with a grafting ratio range of 4.63-14.14 % exhibited bonding forces of 57.8-64.6 N to wool fibers [55.5 N (BBES) and 53.8 N (ATS)], and their films showed breaking elongations of 3.29-3.80 % [2.74 % (BBES) and 2.49 % (ATS)] and tensile strengths of 29.1-25.4 MPa [30.4 MPa (BBES) and 34.7 MPa (ATS)]. Compared with BBES, significantly increased bonding forces and film elongations, and decreased film strengths for the BBES-g-PAA samples with grafting ratios ≥10.54 % were displayed (p < 0.05). The time (100-42 s) taken for the BBES-g-PAA films was significantly shorter than that of ATS (246 s) and BBES (196 s) films (p < 0.05), corresponding to better desizability.
摘要：
如今,介绍了使用电子转移原子转移自由基聚合（ARGETATRP）合成的接枝淀粉的工艺参数及其在经纱施胶和造纸中的应用。因此,本研究旨在调查由ARGETATRP合成的溴代异丁酰基酯化淀粉-g-聚（丙烯酸）（BBES-g-PAA）的合适工艺参数，并且还旨在提供一种新的生物基BBES-g-PAA粘合剂。适宜的合成工艺参数为维生素C摩尔比1.2、0.32和0.6,CuBr2和五甲基二乙烯基三胺到BBES，分别,接枝率范围为4.63-14.14%的BBES-g-PAA样品与羊毛纤维[55.5N(BBES)和53.8N(ATS)]的结合力为57.8-64.6N,膜的断裂伸长率为3.29-3.80%[2.74%(BBES)和2.49%(ATS)],拉伸强度为29.1-25.4MPa[30.4MPa(BBES)和34.7MPa(ATS)]。与BBES相比,显着增加的结合力和薄膜伸长率，显示接枝率≥10.54％的BBES-g-PAA样品的膜强度降低（p<0.05）。BBES-g-PAA膜的时间（100-42s）明显短于ATS（246s）和BBES（196s）膜（p<0.05），对应于更好的可设计性。
