ORGANIC-INORGANIC COMPOSITE COMPOSITION, MANUFACTURING METHOD OF MOLDED ARTICLE, AND OPTICAL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an organic-inorganic composite composition that has a high light transmittance and a high refractive index and exhibits excellent mold releasability on molding. Ž

SOLUTION: The organic-inorganic composite composition includes a thermoplastic resin, bearing a functional group can form an optional chemical bond with an inorganic fine particle at an end or in a side chain of the polymer, and an inorganic fine particle and satisfies equation (1) [wherein γsp(mN/m) is a polar component of a surface free energy of the composition measured at 25°C and a relative humidity of 60%; α (/K) is an average linear expansion coefficient of the composition at 25-50°C; and E (N/m2) is a Young's modulus of the composition measured at 25°C and a relative humidity of 60%].
