Polymeric composition comprising metal alkoxide condensation product, organic silane compound and boron compound

A polymeric composition comprising:

• a reaction product (c) obtained by reacting (a) an organosilane compound represented by the following formula:
• R4-n—Si—(OR′)n
• wherein R represents an organic group containing an amino group;
• R′ represents a methyl group, an ethyl group or a propyl group;
• and n is an integer selected from 1 to 3;
• with (b) at least one boron compound selected from the group consisting of H3BO3 and B2O3,
• wherein the organosilane compound of component (a) is at least one organosilane compound selected from the group consisting of γ-aminopropyltriethoxysilane and N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane,
• wherein the components (a) and (b) are reacted in a molar ratio of (a):(b) of 1:0.02 to 8;
• and
• (d) a condensation product of a metal alkoxide represented by the following formula (d1):
• wherein R1 represents independently an alkyl group, part of which may be hydrogen, and R1 may be identical to or different from each other;
• m is an integer selected from 2 to 20;
• and M represents at least one metal selected from the group consisting of Si, Ti and Zr, wherein the metal alkoxide condensation product (d) is a condensation product of tetraethoxysilane or tetramethoxysilane,
• wherein the condensation product of a metal alkoxide (d) is contained in an amount of 4 to 50 mol, calculated in terms of weight of the metal alkoxide monomer, per mol of component (a).
