| 摘要 |
The present invention relates to a cross-linked acrylic based nanoparticle composition to improve foam possibility and moldability of a vinyl chloride based resin, a cross-linked acrylic based nanoparticle manufactured therefrom, an acrylic based processing aid composition including the cross-linked acrylic based nanoparticle and acrylic based copolymers and a vinyl chloride based resin composition including the same. According to the present invention, the acrylic based processing aid composition is allowed to improve processing by increasing melting pressure of the vinyl chloride based resin composition, when the vinyl chloride based resin composition with the acrylic based processing aid composition is foamed and extruded, and decreases the share of foaming and makes the size of cells small and uniform, thereby improving foam moldability. The acrylic based processing aid composition includes the cross-linked acrylic based nanoparticle and is accordingly used as an additive for improving foam possibility and moldabilty of the vinyl chloride based resin composition. |
