Abstract
The present disclosure relates to a resin composition including a base resin including a first graft copolymer, a second graft copolymer and a maleimide-based copolymer; a polyolefin elastomer; a polyolefin graft copolymer; and a polyolefin wax. The present disclosure also relates to a molded product molded from the resin composition.
Claims4
A resin composition comprising:
- a base resin comprising:
- 40 wt % to 80 wt % of a first graft copolymer that is a bulk polymerized copolymer,
- 1 wt % to 30 wt % of a second graft copolymer that is a emulsion polymerized copolymer,
- 5 wt % to 40 wt % of a maleimide-based copolymer, and
- 1 wt % to 30 wt % of a styrene-based copolymer comprising an aromatic vinyl-based monomer unit and a vinyl cyanide-based monomer unit;
- 0.1 parts by weight to 10 parts by weight, based on 100 parts by weight of the base resin, of a polyolefin elastomer including a copolymer of ethylene and an alpha olefin of 3 to 8 carbon atoms;
- 0.1 parts by weight to 10 parts by weight, based on 100 parts by weight of the base resin, of a polyolefin graft copolymer including a polyethylene-based acrylonitrile-styrene copolymer;
- and
- 0.1 parts by weight to 10 parts by weight, based on 100 parts by weight of the base resin, of a polyolefin wax that includes a polyethylene wax,
- wherein the first graft copolymer comprises;
- 5 wt % to 30 wt % of a rubbery polymer,
- 5 wt % to 30 wt % of a vinyl cyan-based monomer unit, and
- 40 wt % to 90 wt % of an aromatic vinyl-based monomer unit,
- wherein the second graft copolymer comprises:
- 40 wt % to 80 wt % of a rubbery polymer,
- 1 wt % to 30 wt % of a vinyl cyanide-based monomer unit, and
- 10 wt % to 50 wt % of an aromatic vinyl-based monomer unit, and
- wherein the maleimide-based copolymer comprises:
- a maleimide-based monomer unit,
- an aromatic vinyl-based monomer unit, and
- a maleic anhydride monomer unit.
