The present invention, (1) vinyl oligosiloxane hybrid; (2) organohydrogensilicon compounds containing at least two silicon-bonded hydrogens; And (3) metal catalyst; relates to an optical transparent siloxane resin composition comprising.n n n In detail, the vinyl oligosiloxane hybrid of an inorganic mesh structure with high degree of condensation is manufactured by the non-aqueous condensation reaction of organosilanediol and the organoalkoxysilane containing a vinyl group. Moreover, when using the mixture which substituted a part of the organoalkoxysilane containing a vinyl group by the metal alkoxide, the optically transparent siloxane resin which has high condensation degree and high refractive index can be manufactured. The optically transparent siloxane resin according to the present invention has an excellent light transmittance, light resistance and heat resistance, has a refractive index and hardness suitable for optical applications, and has a low shrinkage rate during molding, which is an ideal resin for optical applications such as optical devices, displays, and LEDs. to be.n n n Vinyl oligosiloxane hybrid, condensation reaction, organoalkoxysilane, organosilanediol, metal alkoxide, organohydrogensilicon compound, hydrogen silicide reaction, transparent siloxane resin |
