The catalytic transformation pathway can change to decrease the yield of hydrogen and yield methyl-contained sulfides such as methyl mercaptan, dimethyl sulfide and dimethyl disulfide, but overlarge concentration of methanol would holdback the transformation of isobutyl mercaptan. The transformation of isobutyl mercaptan was favorable if the volume ratio of methanol and benzene was 0.2.The addition of methanol assume certain effect on the catalytic cracking of di-n-butyl sulfide in solvent benzene but without changing the cracking reaction mechanism of di-n-butyl sulfide.

The unirradiated and irradiated samples are analyzed by FTIR, SEM, PGC/MS and TG. At the same time, the gas products after irradiation are analyzed by GC/MS. The relationship of gel fraction of irradiated samples in air with the dose and the compression property and stress relaxation ratio along with the dose are determined.
