Abstract

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 s−1 and a processing temperature of the resin blend, and that has a difference in glass transition temperature from the first resin of 10° C. to 150° C. The resin blend can improve mechanical and surface characteristics of a resin article.

First claim

What is claimed is:

1. A resin article comprising:
a first resin; and
a second resin that is a (meth)acrylate-based resin to which at least one organic functional group selected from the group consisting of tertiary butyl group, isobutyl group, isobornyl group, cyclohexyl group, and phenyl group 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 s −1 at a processing temperature of the resin blend, and that has a difference in glass transition temperature from the first resin of 10° C. to 100° C.,
wherein the first resin includes an acrylate-based resin,
wherein the resin article has a layer-separated structure in which the first resin is disposed inside of the layer-separated structure and the second resin is disposed on a surface of the layer-separated structure during melt processing under shear stress, and has an impact resistance of 6.7 to 8.8 kg*cm/cm in an IZOD ⅛″ test and of 6.5 to 9.1 kg*cm/cm in an IZOD ¼″ test measured according to ASTM D256, and a pencil hardness of 2H to 3H measured according to ASTM 3363-74.

2. The resin article of claim 1 , wherein the second resin has a difference in melt viscosity from the first resin of 0.1 to 2000 pa*s at a shear rate of 100 to 1000 s −1 at a processing temperature of the article.

3. The resin article of claim 1 , wherein the second resin is a (meth)acrylate-based resin having a tertiary butyl group functional group.

4. The resin article of claim 1 , wherein the second resin is a (meth)acrylate-based resin having an isobornyl functional group.

5. The resin article of claim 1 , wherein the second resin is a (meth)acrylate-based resin having a cyclohexyl functional group.

6. The resin article of claim 1 , wherein the second resin is a (meth)acrylate-based resin having a phenyl functional group.
