摘　　要：The degradation of ultra - high molecular weight polyethylene (UHMW- PE) during its dissolution into deca-lin is discussed. Also is discussed the stabilization of thesolution by three phenolic antioxidants, octadecyl β - (3, 5 - di - tert - butyl - 4 - hydroxyphenyl) propionate(1076), tetrakis[methylene β-(3,5-di-t-butyl-4- hydroxyphenyl) - propionate] methane(1010), 1,1,3-tris(2-methyl- 4- hydroxy- 5- tert-butylphe-nyl)butane (CA), and an auxiliary antioxidant.dilauryl-thio- dipropionate(DLTP). Among the three phenolic antioxidants, the effect of 1076 is the greatest) and the auxiliary antioxidant is effective in the stabilizing the solution when combined with one of the three phenolic antioxidants.The degradation of ultra - high molecular weight polyethylene (UHMW- PE) during its dissolution into deca-lin is discussed.
