    • PURPOSE: To obtain the titled composition having improved mechanical characteristics and weather resistance in high yield of polymerization from easily synthesizable raw materials, by compounding a curing catalyst to a copolymer obtained by the epoxy ring-opening copolymerization of a specific epoxide compound and a specific epoxy-containing silane.
      CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a copolymer obtained by compounding (i) an epoxy compound of formula I (X is univalent hydrocarbon group which may contain an ether O atom, or H) and (ii) an epoxy-containing silane of formula II (R
      1 and R
      2 are substituted or unsubstituted univalent hydrocarbon group; R
      3 is bivalent hydrocarbon group; Y is univalent substituted hydrocarbon group which contains an oxirane oxygen and may contain an ether oxygen atom at the part bonded to R
      3 ; n is 0, 1 or 2) wherein the ratio of (ii) to (i) is 0.01W20mol%, preferably 0.05W2mol%, with (B) 0.01W20pts.wt. of a curing catalyst capable of curing the composition by accelerating the hydrolysis of -OR
      2 group of the component A.
