Patent ID: 7595285

Claim:
A combination of a thermoplastic resin composition with a lubricating oil comprising: (a) a lubricating oil in contact with (b) a thermoplastic resin composition, wherein the thermoplastic resin composition comprises: a fluororesin in an amount ranging from 5 to 40 parts by weight, the fluororesin including a crosslink formed between at least a part of a molecule chain of the fluororesin and at least a part of another molecular chain of the fluororesin, and active end groups that form at least a part of the molecule chain of the fluororesin; and a thermoplastic resin other than a fluororesin, in an amount ranging from 95 to 60 parts by weight, wherein at least a part of the active end groups of the fluororesin is chemically bonded with a part of the thermoplastic resin; and wherein the thermoplastic resin has a surface energy ranging from a first value of [a surface energy of the lubricanting oil+0] N/cm to a second value of [the surface energy of the lubricanting oil+20×10 5 ] N/cm.
