Resin composition and molded product
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.
1 . 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:

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.
