Provided are a resin blend for forming a layer-separated structure, a pellet, a method of preparing a resin article using the same and a resin article. The resin blend may include a first resin, and a second resin that comprises a resin to which at least one organic functional group selected from the group consisting of an alkyl group having 2 to 20 carbon atoms, an alicyclic group having 5 to 40 carbon atoms and an aromatic group having 6 to 40 carbon atoms is introduced, that has a difference in melt viscosity from the first resin of 0.1 to 3000 pa*s at a shear rate of 100 to 1000 sand a processing temperature of the resin blend, and that has a difference in glass transition temperature from the first resin of 10&#xb0; C. to 150&#xb0; C. The resin blend can improve mechanical and surface characteristics of a resin article.

Resin blend for melting process

The present invention relates to a resin blend for a melting process, to a method for manufacturing a resin molding using same, and to a resin molding obtained thereby, the resin blend comprising a first resin and a second resin, wherein the second resin includes a polymer resin having at least one organic functional group selected from the group consisting of an alkyl group having 2 to 20 carbon atoms, an alicyclic ring having 5 to 40 carbon atoms and an aromatic ring having 6 to 40 carbon atoms, and has, with the first resin, a melt viscosity difference of 0.1 to 3,000 Pa*s at a shear rate of 100 to 1,000 sand a processing temperature of the resin mixture, and a glass transition temperature (T) difference of 10&#xb0; C. to 150&#xb0; C.

Disclosed are an alkyl(meth)acrylate-based thermoplastic resin composition and a thermoplastic resin with modified scratch resistance and yellowness. The alkyl(meth)acrylate-based thermoplastic resin composition provides improved scratch resistance and low yellowness index while maintaining transparency, flowability, and impact strength, even when the total content of the vinyl cyan-based monomer contained in the resin composition is reduced to a level unattainable by conventional techniques, and the content of the alkyl(meth)acrylate-based monomer is increased.
