Abstract
This invention relates to expanded polyester materials comprised of polyester/acrylic elastomer blend having an improved ductility and impact resistance, while the compression strength, shear strength/modulus of polyesters remain almost unchanged or unworsened. Addition of a non-reactive/reactive acrylic mixture serving as the blend partner improves the melt strength in an expanding process and leads to a better impact resistance of expanded aromatic polyester materials. All expanded polyester materials are produced with help of a reactive process.
