Abstract
Official abstract text for this publication.
The present invention relates to a polycarbonate resin composition. The polycarbonate resin composition exhibits excellent optical properties, and thus can be used as a material for a light guide plate.
First claim
Opening claim text (preview).
1 . A polycarbonate resin composition comprising: polycarbonate and 1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane. 2 . The polycarbonate resin composition of claim 1 , wherein the 1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane is contained in an amount of 0.01 to 0.3 parts by weight based on 100 parts by weight of the polycarbonate. 3 . The polycarbonate resin composition of claim 1 , wherein the resin composition further includes an antioxidant, a hydrolysis-resistant agent, a brightness-improving agent or a mixture thereof. 4 . The polycarbonate resin composition of claim 3 , wherein the antioxidant is a phenol-based antioxidant, a phosphorus-based antioxidant, a thio-based antioxidant, or a mixture thereof. 5 . The polycarbonate resin composition of claim 3 , wherein the antioxidant is contained in an amount of 0.01 to 0.15 parts by weight based on 100 parts by weight of the polycarbonate. 6 . The polycarbonate resin composition of claim 3 , wherein the hydrolysis-resistant agent is an epoxy group-containing polymer. 7 . The polycarbonate resin composition of claim 3 , wherein the hydrolysis-resistant agent is contained in an amount of 0.02 to 0.2 parts by weight based on 100 parts by weight of the polycarbonate. 8 . The polycarbonate resin composition of claim 3 , wherein the brightness-improving agent is a polymer containing oxyalkylene repeating units. 9 . The polycarbonate resin composition of claim 3 , wherein the brightness-improving agent is contained in an amount of 0.1 to 0.5 parts by weight based on 100 parts by weight of the polycarbonate.
