Abstract
A foamable polyester resin composition comprising (A) 100 parts by weight of a polyester resin, (B) from 0.5 to 30 parts by weight of a (meth)acrylic ester polymer or a polymer mixture obtained by polymerizing from 0 to 50 parts by weight of a monomer mixture (b) in the presence of a polymer latex which is obtained by emulsion-polymerizing from 50 to 100 parts by weight of a monomer mixture (a) wherein, when 0.1 g of the polymer is dissolved in 100 mL of chloroform, the resulting solution has a specific viscosity of from 0.7 to 1.9 as measured at 30° C. (wherein the sum of the monomer mixtures (a) and (b) being 100 parts by weight), wherein, when 0.1 g of the (meth)acrylic ester polymer or the polymer mixture is dissolved in 100 mL of chloroform, the resulting solution has a specific viscosity of from 0.65 to 1.7 as measured at 30° C., (C) from 0.1 to 30 parts by weight of a filler, (D) a blowing agent.
