A polyester resin having a good impact strength and molding processabilities was prepared. 30-80 Wt.% of a polyester resin having a limiting viscosity of 0.4-1.2, 5-30 wt.% of polyester copolymer resin(I) polymerized by terephthalic acid, butanediol and polytetraglycol, 2-20 wt.% of a thermoplastic elastomer, 1-10 wt.% of phosphoric compound(II), 5-30 wt.% of a flame retardant having the ratio of decabromodiphenyl oxide(III) and antimony trioxide of 1:1-5:1, 5-50 wt.% of a glass fiber. The surface was treated with silane compound having an organic functional group, a length of 2-8 mm and a diameter of 7-15um , a stabilizer containing tetrakis[methylene-3,5-di-t-butyl-4-hydroxyphenyl)propionate methane and tris(2,4-di-t-butylphenyl)phosphite in the ratio of 1:1, 0.1-5 wt.% of ethylene-bis-stearamide, and aluminium stearate as releasing agent, were mixed and extruded at 230-270 deg.C. Where X is 4,5, n and m are 10-50, a is 20-100, R1 is C1-30 aliphatic alkyl, R2 is H or C1-30 aliphatic alkyl, and R1 and R2 is can be identical or different.
