摘　　要：本文研究不同增韧剂对环烯烃类共聚物(COC)的力学性能的影响,并对比了ABS、PC的力学性能和耐化学溶剂性。结果表明,相较于COC试样,增韧改性试样的拉伸强度降低、断裂伸长率提高、弯曲性能明显降低及悬臂梁缺口冲击性能提高,表明增韧剂的引入发挥了显著的增韧效果;增韧改性试样的强度和模量与ABS试样接近一致,在常低温冲击韧性方面表现更加优异,但与PC试样仍然存在一定的差距;COC/SEBS试样表面观察不到断裂、微裂纹,ABS试样均能观察到表面断裂、微裂纹,表明COC/SEBS试样具有更优异的耐化学溶剂性能。The study investigated the influence of different toughening agents on the mechanical properties of cyclic olefin copolymer(COC),comparing them with acrylonitrile butadiene styrene(ABS)and polycarbonate(PC)in terms of mechanical performance and chemical solvent resistance.Results indicated that compared to pure COC specimens,toughened modified specimens exhibit decreased tensile strength,increased elongation at break,significantly reduced flexural properties,and enhanced notch impact strength,suggesting a notable toughening effect due to the introduction of toughening agents.The strength and modulus of toughened modified specimens were comparable to ABS specimens,demonstrating superior performance in low-temperature impact toughness,although still exhibiting some disparity with PC specimens.Observation of the surfaces of COC/SEBS specimens reveals no visible fractures or microcracks,while surface fractures and microcracks were evident in ABS specimens,indicating superior chemical solvent resistance in COC/SEBS specimens.
