<p>Disclosed are a novel modified polysiloxane-based copolymer which can be used in improving the heat resistance, chemical resistance, optical transmittance, and hardness of a polymer plastic material, a coating composition including this copolymer , a coated plastic substrate obtainable by using the same and a method for preparing the same, and a method for preparing the novel modified polysiloxane-based copolymer. The novel polysiloxane-based copolymer has an organic/inorganic hybrid polymer properties including both of a Si-C bond and a Si-O group, and a coating film including a cured product thereof can provide a typical organic polymer plastic film with heat resistance, chemical resistance, high optical transmittance, and high hardness.</p> |
