The present invention relates to an acrylic processing aid, a method for preparing the same, and a polyvinyl chloride resin composition comprising the same. More specifically, the present invention relates to an acrylic processing aid having a core-shell structure comprising the core and shell comprise a polymer prepared by copolymerizing a methyl methacrylate monomer and an alkyl acrylate monomer having 1 to 18 carbon atoms, and wherein the core comprises the polymer having a weight-average molecular weight ranging from 10,000,000 to 18,000,000 g/mol, a method for preparing the same, and a polyvinyl chloride resin composition comprising the same.

The present invention relates to resin-modifying particles, each of which contains a glycidyl group-containing polymer (B) and a core-shell copolymer (C) at a composite state, and a vinyl chloride resin composition containing a vinyl chloride resin (A) and the resin-modifying particles, and the like.

The present invention relates to a thermoplastic composition, a thermoplastic composite, and a method for producing the thermoplastic composite. In the method for producing the thermoplastic composite, a polymer, an acid-modified lignin with a specific element content and a compatibilizer with a specific melt flow index and a specific maleic anhydride content are used to produce the thermoplastic composite. Hydroxy groups of the acid-modified lignin react with maleic anhydride groups of the compatibilizer to generate ester bonds via an in-situ reaction catalyzed by acidic groups of the acid-modified lignin to enhance compatibility between the polymer and the lignin, thereby increasing a mechanical strength of the resulted thermoplastic composite.
