摘要:
A silicone-based impact modifier including a core-shell graft copolymer is disclosed. The silicone-based impact modifier includes a core made of a silicone-based rubber and alkyl acrylate and a shell made from an inorganic acrylate compound. Also disclosed is a thermoplastic resin composition including the silicone-based impact modifier.

One aspect of the invention relates to a method of preparing silicone fine particles which comprises preparing a mixture comprising an organotrialkoxysilane and an organochlorosilane to give a concentration of the organochlorosilane in the mixture of about 100 to about 2,000 ppm; mixing the mixture with water to prepare a sol solution; and maintaining a pH value of the sol solution within a range of about 8 to about 11. Another aspect of the invention relates to a thermoplastic resin composition which employs the silicone fine particles as a diffuser.

摘要:
Acrylic fine particles formed by polymerization of a (meth)acrylate containing monomer with a cross-linking agent are disclosed. The cross-linking agent includes a first cross-linking agent having at least three (meth)acryloyloxy groups and at least one functional group —OH, —COOH, or a combination thereof, and the acrylic fine particles can have a coefficient of variation (C.V.) of about 20 to about 60%. The acrylic fine particles can have high heat resistance and solvent resistance and also enhanced compatibility with a binder and a solvent. Accordingly, the acrylic fine particles can exhibit remarkably increased dispersibility when used in a diffusing film or the like, and thus are suitable for use as a diffusing agent.

摘要:
Disclosed herein is a silicone particle with excellent hydrophobic and alkali proof properties. The present invention provides a method of controlling surface hydroxyl groups by treating the surface of silicone particles with alkali metal ions or alkaline earth metal ions. The present invention also provides a coating composition using the silicone particle, in which the amount of hydroxyl groups present on the surface of the silicone particle can be controlled.
