通过将不同摩尔配比的丙烯酸(AA)与丙烯酸乙酯(EA)单体接枝到具有相同取代度的烯丙基醚化淀粉(AS)的分子链上,制备出一系列具有不同结构接枝支链的AS-g-P(AA-EA)三元接枝共聚物。然后,以淀粉溶液在聚酯纤维上的接触角、淀粉膜的拉伸力学性能以及淀粉对聚酯纤维的粘合强度为主要量化指标,系统研究了AA/EA单体配伍对AS-g-P(AA-EA)与聚酯纤维粘合性能的影响。结果表明:当AA/EA单体的投料摩尔比为2∶8时,合成出的AS-g-P(AA-EA)对聚酯纤维的粘合性能较为优异。
By grafting acrylic acid (AA) and ethyl acrylate (EA) with different mole ratio onto the molecular chain of allyl etherified starch (AS) with the same degree of substitution, a series of copolymers with different structure Branched branched AS-gP (AA-EA) ternary graft copolymer. Then, the contact angle of starch solution on polyester fiber, the tensile mechanical properties of starch film and the adhesive strength of starch to polyester fiber are the main quantitative indexes. The effect of AA / EA monomer on AS-gP AA-EA) and polyester fiber adhesive properties. The results showed that AS-g-P (AA-EA) synthesized by AA / EA monomer had better adhesion to polyester fiber when the molar ratio of AA / EA was 2: 8.
