  • Oil-containing resin and its composition
    Patent number: 4829093
    Abstract: The present invention provides an oil-containing resin having a flowability of not more than 45.degree. in terms of an angle of repose, which comprises a porous styrene-divinylbenzene copolymer and a liquid oil adsorbed on the copolymer, an oil-containing resin mixture in a paste form of the oil-containing resin and a liquid oil, and a composition of the oil-containing resin mixture in a paste form and a thermoplastic resin. Owing to a good flowability, the oil-containing resin has a good moldability, and also owing to a high oil content, a molding having distinguished sliding characteristics is obtained from the composition of the oil-containing resin mixture in a paste form and a thermoplastic resin.
