据《Polym．Ddgrad．Stab．》1997，58，181－185报道，巴西学者采用热重分析法研究了聚[乙烯－乙烯醇共聚物）－甲基丙烯酸甲酯]（EVAL－g－PMMA）的热稳定性。接技共聚物是在硫氢基改性的乙烯一乙烯醇共聚物（EVALSH）作为传递剂存在下通过MAM的自由基聚合来制备的。在接技共
According to “Polym. Ddgrad. Stab. ”1997, 58, 181-185 reported that Brazilian scholars studied the thermal stability of poly [ethylene-vinyl alcohol copolymer) -methyl methacrylate] (EVAL-g-PMMA) by thermogravimetric analysis. The graft copolymer was prepared by free radical polymerization of MAM in the presence of a sulfhydryl-modified ethylene vinyl alcohol copolymer (EVALSH) as a delivery agent. In the access technology
