Q is a single bond or a bivalent linking group;
R1 is a hydrogen atom or a monovalent C1-16 organic
group;
a is 1 or 2;
b is 0 or 1, and (a+b) is 1 or 2; and
X1 is a hydrolysable group;
wherein a proportion (T1) of a molecule with a
molecular weight of at most 2M in the partial
hydrolysate is less than 70% as calculated from
Formula (A), wherein M is a molecular weight of the
fluorine-containing reactive silane measured by gel
permeation chromatography:
T1(%)=[W2/W1]x100 Formula (A);
wherein
W1 is a total peak area within a molecular weight
range of from 300 to 100000 on a gel permeation
chromatogram of the partial hydrolysate of the
fluorine-containing reactive silane; and
W2 is a total peak area within a molecular weight
range of from 300 to 2M on a gel permeation
chromatogram of the partial hydrolysate of the
fluorine-containing reactive silane;
wherein a proportion (T2) of a molecule with a
molecular weight of at least 6M in the partial
hydrolysate is less than 10% as calculated from
Formula (B):
T2(%)=[W3/W1]x100 Formula (B);
wherein
W1 is a total peak area within a molecular weight
range of from 300 to 100000 on a gel permeation
chromatogram of the partial hydrolysate of the
fluorine-containing reactive silane; and
W3 is a total peak area within a molecular weight
range of from 6M to 100000 on a gel permeation
chromatogram of the partial hydrolysate of the
fluorine-containing reactive silane; and
wherein the partial hydrolysate is obtained by
partial hydrolysis of the fluorine-containing reactive
silane in the presence of water and nitric acid.
