Abstract
A rotomolded article can have one or more layers, including a layer A. The layer A can have from 50 to 99.4 wt % of a polyolefin, from 0.5 to 50 wt % of a polyester, and from 0.1 to 20 wt % of a co- or ter-polymer. The co- or ter-polymer can have 50 to 99.9 wt % of an ethylene or a styrene monomer, 0.1 to 50 wt % of an unsaturated anhydride-containing monomer, epoxide-containing monomer or carboxylic acid-containing monomer, and 0 to 50 wt % (meth)acrylic ester monomer.
Claims23
A rotomoulded article having one or more layers comprising:
- a layer A that comprises:
- from 50 to 99.4 wt % of a polyolefin;
- from 0.5 to 50 wt % of a poly(lactic acid), wherein the poly(lactic acid) comprises an optical purity of at least 92 wt %;
- and
- from 0.1 wt % to no more than 5 wt % of a ter-polymer that comprises:
- 50 to 99.9 wt % of styrene monomer;
- 0.1 to 50 wt % of an unsaturated anhydride-containing monomer, epoxide-containing monomer or carboxylic acid-containing monomer;
- and
- 0.1 to 50 wt % of a (meth)acrylic ester monomer, wherein the (meth)acrylic ester monomer is methyl (meth)acrylate, ethyl (meth)acrylate, n-butyl (meth)acrylate, iso-butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, or n-octyl (meth)acrylate.
