发明名称 Core-shell resin pellet having melt viscosity difference between the core resin and the shell resin
摘要 Provided are a resin blend for melt processing, a pellet and a method of preparing a resin article using the same. The resin blend may include a first resin, and a second resin having 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. The resin blend can improve mechanical and surface characteristics of a resin article. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.

主权项 1. A pellet, comprising: a core including a first resin; and a shell including a second resin having a molecular weight distribution of 1 to 2.5 and 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 pellet.
