PURPOSE:To remarkably improve storage stability of a silane-modified polyamide resin, by adding a dried zeolite powder to a silane-modified polyamide resin having hydrolyzable silyl group, thereby suppressing hydrolytic crosslinking reaction caused by moisture. CONSTITUTION:(A) 100pts.(wt.) of a silane-modified polyamide resin powder having one or more hydrolyzable silyl group of formula I (R is aliphatic hydrocarbon group, alicyclic hydrocarbon group or aromatic hydrocarbon group; a is 0-2; X is hydrolyzable group) in a molecular chain and produced by the addition reaction of gamma-isocyanatopropyl triethoxysilane, etc., to a polyamide resin having amino group at a terminal and containing <=0.2% moisture is added with (B) 0.1-10pts., preferably 1-5pts. of dried zeolite powder produced by calcining natural or synthetic zeolite at >=250 deg.C to effect sufficient dehydration of the powder.
