求翻译:引发剂用量过大,容易导致与接枝链活性末端的偶合,加速链终止反应,导致交联密度的增加,相对分子量降低,可能还会使活性中心来不及聚合便终止[101 ,102] ,使得淀粉上接枝的链多为短链,无法形成有效的交联网状结构,使吸水率也趋于减少。另外剩余的引发剂也会作为电解质残存于树脂中,使吸水倍数降低。是什么意思?

待解决 悬赏分:1 - 离问题结束还有

Initiator with excessive activity easily lead to the end of the graft chain coupling, accelerating chain termination reaction, leading to an increase in crosslink density, molecular weight reduction, may also be too late to make the active center of polymerization will be terminated [101, 102], so S

initiating agent, it will easily lead to excessive consumption and the sticks of chain reaction at the end was no coincidence, accelerate chain reactions that result in the termination of an increase in the density and Relative molecular weight reduction may also lead to reactive Center polymerizati

The initiator amount used oversized, easy to cause with the stem grafting chain active terminal coincidence, the acceleration chain termination reaction, causes the crossing linking density the increase, the relative molecular weight reduces, possibly also can cause the active center to get together

Raised agent dosage had large, easy led and received branch chain activity ends of coupled, accelerated chain terminated reaction, led cross joint density of increased, relative molecular volume reduced, may also will makes activity center too late aggregate will terminated [101, 102], makes starch
