Abstract: A polymer composition containing a specific silyl group-containing polymer, in which the maximum size of particles contained therein is 2 nullm or less, and the number of particles having a size of 0.2 nullm to 2 nullm is 1,000 particles/ml or less. The composition may further contain a specific compound or at least one component selected from an organosilane represented by (R1)nSi(X)4-n, a hydrolyzate of the organosilane and a condensate of the organosilane. The composition is excellent in storage stability, high in hardness and excellent in mechanical strength such as wear resistance, so that a coating film having good taking-up properties even when no lubricant is contained, extremely smooth and having no difference in film thickness can be formed.
