PROBLEM TO BE SOLVED: To obtain a copolymer composition having excellent characteristics of a polypeptide and a silicone compound and other characteristics based on a silane compound, readily producible in a water system. ;SOLUTION: One or more organosilane compounds containing a hydrophilic group of formula I: R¹(3-m)Si(OH)_mA-B [(m) is 2 or 3; (3-m)×R¹ groups are each an alkoxy group, a hydrogen atom or a 1-3C alkyl group; A is a direct bond and a group such as methylene group, propylene group or the like; B is a hydrophilic organic group] and one or more silane compounds of formula II: R²nSi(OH)pY(4-p-n) [(n) is 0-2, (p) is 2-4, n+p≤4; R² is an organic group containing carbon atom directly bonded to silicon atom; (4-p-n)×Y groups are each an alkoxy group, hydrogen or siloxy group] are subjected to condensation polymerization to produce a silane compound copolymer composition. Preferably, B in formula I is a polypeptide having 100-5,000 number-average molecular weight.;COPYRIGHT: (C)1999,JPO
