Fine particles for modifying polyolefine

摘要

A fine particle for modifying polyolefine is provide. The fine particle comprises (i) a core layer having a refractive index which differs from that of the polyolefine by 0.05 or less and (ii) a shell layer having a solubility parameter which differs from that of the polyolefine by 3 MPa½ or less, wherein the core layer is coated with the shell layer. The fine particle is excellent in affinity with polyolefine, and can modify polyolefine without accompanying damage on the transparency of the polyolefine.
