A spontaneous combination of hygienic in situ compatibilized polybutylene succinate/polylactic acids (PBS/PLA) was formulated through the addition of optimum dosages of dicumyl peroxide (DCP), which was a fundamental motivator, and 2-hydroxypropyl-3-piperazinyl-quinoline carboxylic acid methacrylate (HPQM) as an antibacterial agent via a melt blending process. The effect of reprocessing the mechanical and natural attributes, as well as the hygienic effectiveness to counter the Escherichia coli of the PBS/PLA combinations were explored. The outcomes demonstrated that varying processing cycles affected the rupture performance of the PBS/PLA blends. Furthermore, the toughness of the PBS/PLA blends rose as the number of cycles escalated. Three processing cycles exhibited the highest elongation at the break and tensile toughness, while the number of processing cycles did not have any major negative impact on the tensile modulus and strength. For the effect of the number of the processing cycles of the hygienic effectiveness against the E. coli on the PBS/PLA blends doped with HPQM, the percentages of bacterial reduction appeared to rise as the contact time was increased, but decreased with the increasing number of cycles. The study suggested that the PBS/PLA blends could be reprocessed up to three times and still retain their optimal properties.

通过添加最佳剂量的过氧化二异丙苯 (DCP) 和 2-羟丙基-3-哌嗪基-喹啉羧酸，配制了卫生原位相容的聚丁二酸丁二醇酯/聚乳酸 (PBS/PLA) 的自发组合通过熔融共混工艺将甲基丙烯酸酸 (HPQM) 作为抗菌剂。再加工机械和自然属性的效果，以及对抗大肠杆菌的卫生效果研究了 PBS/PLA 组合。结果表明，不同的加工周期会影响 PBS/PLA 共混物的断裂性能。此外，PBS/PLA 混合物的韧性随着循环次数的增加而增加。三个加工循环表现出最高的断裂伸长率和拉伸韧性，而加工循环次数对拉伸模量和强度没有任何重大负面影响。对于对大肠杆菌的卫生有效性的处理周期数的影响在掺有 HPQM 的 PBS/PLA 共混物中，细菌减少的百分比似乎随着接触时间的增加而增加，但随着循环次数的增加而减少。该研究表明，PBS/PLA 混合物最多可再加工 3 次，并且仍能保持其最佳性能。
