Abstract

An at least two layer rotomolded article is described herein which may include a layer A and a layer B. Layer A can include an aliphatic polyester, a polyolefin, or a co- or ter-polymer that includes ethylene or styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer. Layer B can include a polyolefin and a polyester, or a co- or ter-polymer that includes an ethylene or a styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer.
