The present disclosure relates to a matting agent including emulsion polymer particles, a matting polymer composition including a matting agent, and a method of producing emulsion polymer particles. The emulsion polymer particles may be produced by a simple process using an emulsion polymerization method, and have the advantage of being relatively easy to control a degree of crosslinking. In addition, in a case where a matting polymer composition is prepared using a matting agent including the emulsion polymer particles, it is possible to manufacture a molded article having excellent appearance and matting effect without deterioration of the existing mechanical properties such as impact strength and tensile strength of a thermoplastic polymer, and in particular, an excellent matting effect may be exerted even in the extrusion processing, which has been difficult to achieve in the related art.

The present disclosure relates to a matting agent including polymer particles, a matting polymer composition including a matting agent, and a method of producing polymer particles. The polymer particles may be produced by a simple process using a suspension polymerization method, and is relatively easy to control a degree of crosslinking. In addition, in a case where a matting polymer composition is prepared using a matting agent including the polymer particles, it is possible to manufacture a molded article having excellent appearance and matting effect without deterioration of the existing mechanical properties such as impact strength and tensile strength of a thermoplastic polymer, and in particular, an excellent matting effect may be exerted even in the extrusion processing, which has been difficult to achieve in the related art.

Matting agent including polymer particles, matting polymer composition including matting agent, and method of producing polymer particles

The present invention relates to a processing aid of a non-fluorinated melt-processable polymer and a masterbatch for a processing aid, features the inclusion of a processing aid comprising a fluoropolymer forming clustered secondary particles each having a particle size of 2 &#x3bc;m to 2 mm and being a combination of primary fluoropolymer particles each having a diameter of 0.02 &#x3bc;m to 0.5 &#x3bc;m, and may accelerate the elimination of melt fracture despite the omission of an interfacial agent and decrease extrusion load upon process to thereby enhance productability.
