A vinyl chloride resin composition comprising 100 parts by weight of a vinyl chloride resin, from 20 to 200 parts by weight of a plasticizer, from 10 to 250 parts by weight of a rubber material containing from 20 to 95 wt % of a gel content insoluble in tetrahydrofuran, and from 0.5 to 30 parts by weight of an acrylic resin obtained by copolymerizing from 20 to 50 wt % of methyl methacrylate with from 80 to 50 wt % of at least one monomer selected from the group consisting of acrylates, methacrylates (other than methyl methacrylate) and styrene.

Vinyl chloride resin composition

A vinyl chloride resin elastomer composition comprising, as main components, 100 parts by weight of a vinyl chloride resin, from 10 to 200 parts by weight of an acrylic rubber containing a tetrahydrofuran-insoluble cross-linking component, from 1 to 50 parts by weight of an acrylic resin and from 30 to 300 parts by weight of a plasticizer.

Vinyl chloride resin elastomer composition

A resin composite having a soft resin composition combined to a hard resin, wherein the soft resin composition consists essentially of 100 parts by weight of a vinyl chloride resin, from 10 to 400 parts by weight of a rubber material containing at least 30 wt % of a tetrahydrofuran-insoluble rubber component and from 30 to 300 parts by weight of a plasticizer, and the hard resin consists of a chlorinated vinyl chloride resin, or a mixture of a chlorinated vinyl chloride resin and a vinyl chloride resin in which the chlorinated vinyl chloride resin is in an amount of at least 20 wt %.

Resin composite and gasket

A vinyl chloride resin elastomer composition comprises 100 parts by weight of a resin mixture comprising from 50 to 95 parts by weight of a vinyl chloride resin and from 5 to 50 parts by weight of a chlorinated polyethylene; from 20 to 400 parts by weight of an acrylonitrile-butadiene rubber containing a tetrahydrofuran-insoluble crosslinking component; and from 10 to 300 parts by weight of a plasticizer.
