    • The invention discloses a terminal-modified conjugated diene-vinyl aromatic copolymer and a method for manufacturing the same. The method comprises the following steps. An organic alkali metal initiator is added into a first mixture containing a conjugated diene monomer and a vinyl aromatic hydrocarbon monomer to perform reaction to obtain a conjugated diene-vinyl aromatic copolymer with active terminal. The conjugated diene-vinyl aromatic copolymer with active terminal reacts with polysiloxane to obtain a terminal-modified conjugated diene-vinyl aromatic copolymer. The aforementioned polysiloxane is expressed as chemical formula (I): R1, R2, R3 and R5 independently are alkyl group with 1˜20 carbon atoms. R4 is selected from one of alkyl group, alkoxy group or hydroxyl group with 1˜5 carbon atoms, m is an integer of 2˜50, and n is an integer of 0˜50.

    • Provided is a transparent siloxane resin composition for optical applications, including: (1) a vinyl-oligosiloxane hybrid; (2) an organohydrosilicon compound having two or more silicon-bonded hydrogen atoms; and (3) a metal catalyst.A vinyl-oligosiloxane hybrid having an inorganic network structure and a high degree of condensation is prepared via a non-hydrolytic condensation reaction of an organosilanediol and an organoalkoxysilane having a vinyl group. When the organoalkoxysilane having a vinyl group is partly substituted with a metal alkoxide, a transparent siloxane resin for optical applications with high degree of condensation and refractive index can be prepared. The resulting transparent siloxane resin for optical applications exhibits excellent light transmittance, light resistance and heat resistance, has refractive index and hardness suitable for optical applications, and experiences little contraction during processing. Hence, it makes an ideal resin for optical applications, including optical devices, displays, LEDs, or the like.
