Figure 2: (a) Decrease of the IR detector response with time after the addition of the zeolite SH-300 to solutions of polyethylene with an average molar mass of 2.155 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140 C . Symbols: initial mass of polyethylene in the reactor: —7.70 mg; —11.20 mg; —15.30 mg; —20.64 mg; —31.14 mg. (b) Decrease of the IR detector response with time after the addition of the zeolite SH-300 to solutions of polyethylene with an average molar mass of 14 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140°C. Symbols: initial mass of polyethylene in the reactor: —4.8 mg; —10.5 mg; —21.2 mg; —26.1 mg; —30.39 mg. (c) Change of the response of the IR detector with time after the addition of zeolite SH-300 to solutions of polyethylene with an average molar mass of 53.1 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140°C. Symbols: initial mass of polyethylene in the reactor: —6.44 mg; —11.28 mg; —16.64 mg; —22.35 mg; —30.22 mg.
