摘要
本文以(NH4)2S2O8-NaHSO3为引发剂在一定条件下制备得淀粉/PEI共聚物。结果表明共聚物对瓦楞原纸环压强度和裂断长的提高非常有效,在添加量为1%时,环压强度指数和裂断长比空白样可分别提高11.53%和34.26%。
In this paper, the starch/PEI copolymer was synthesized with starch and PEI in （NH4 ）2S2O8 -NaHSO3 initiator system. The result showed that the copolymer was more efficient than cationic starch in ring crush and tensile strength. The ring crush index and breaking length could be improved by 11.53% and 34.26% respectively when the dosage was 1% （based on oven dry pulp）.
