The present invention relates to a polycarbonate resin composition for a light guide plate and an optical molded article using the same. The polycarbonate resin composition according to the present invention is excellent in transmittance and color tone uniformity required as the light guide plate, and also is excellent in processability and thus can be usefully used as a material of the light guide plate.

Polycarbonate resin composition and optical molded article using the same

The present invention relates to a polycarbonate resin composition and an optical molded article comprising the same. The polycarbonate resin composition according to the present invention is excellent in transmittance and color stability and thus can ensure high transparency, and further can enhance the stability of a polycarbonate resin.

The present invention provides a method for preparing a polycarbonate by removing a solvent from a polycarbonate polymerization solution without impairing the physical properties of the polycarbonate.

Method for preparing polycarbonate

Provided are a plasticizer composition including a hydroxypivalyl hydroxypivalate ester and a neopentylglycol ester, and a method of preparing the plasticizer composition. The plasticizer composition provides a polyvinyl chloride resin having excellent properties of heat loss, migration resistance and plasticization efficiency, and tensile strength, elongation, etc.

Hydroxypivalyl hydroxypivalate ester plasticizer composition and method of preparing the same

Provided is a novel triethyleneglycol based compound, a plasticizer composition for polyvinyl chloride resin including the same, and a method of preparing the plasticizer composition. In particular, the plasticizer composition for polyvinyl chloride resin includes the novel compound, 2-(2-(2-(2-ethylhexanoyloxy)ethoxy)ethoxy)ethyl 2-ethylhexanoate, and 2-(2-(2-phenylcarbonyloxyethoxy)ethoxy)ethyl benzoate in a proper mixture ratio. A polyvinyl chloride prepared using the plasticizer composition has low heating loss, excellent adhesion, high plasticization efficiency, high elongation, high tensile strength, and high transparency.
