    摘要： An epoxy resin composition for powder coatings which comprises (a) 40 to 95 parts by weight of a solid epoxy resin having at least two epoxy groups in a molecule, an epoxy equivalent of 400 to 2500, and a softening point of 50.degree. C. to 150.degree. C., and (b) 5 to 60 parts by weight of an epoxidized polydiene polymer having a main structure of general Formula (I) in which aliphatic double bonds are partially epoxidized. Formula (I) is(A--B--Ap)n--Yr--(Aq--B)m (I)in which Y is a coupling agent, a monomer for coupling, or an initiator, A is a polymer block selected from a homopolymer block of a conjugated diolefine monomer, a copolymer block of a conjugated diolefine monomer, a copolymer block composed of a conjugated diolefine monomer and an aromatic hydrocarbon monomer having one alkenyl group, B is a polymer block selected from a homopolymer block of an aromatic hydrocarbon monomer having one alkenyl group or a copolymer block thereof, or a copolymer block composed of an aromatic hydrocarbon having one alkenyl group and a conjugated diolefine monomer, n is not less than 0, r is 0 or 1, and m is 0 or more, the total of n and m is 1 to 100, and p and q are 0 or 1).
