Abstract
Poly(meth)acrylate formulations include acrylic copolymers having acrylic monomer units including xanthate, thiocarbonylthio, disulfide, or dithioester functionality. The acrylic copolymers can be blended with poly (meth)acrylate resins to provide a blended composition having a healable property. The xanthate, thiocarbonylthio, disulfide, or dithioester functionality can be activated by the addition of energy, such as heat, or radiation, to remove marring from the surface of a coating, film, or sheet.
Claims13
A copolymer composition comprising:
- a) a copolymer comprising:
- 1) at least one thio-functional monomer comprising at least one of trithiocarbonate (TTC)-acrylate;
- 2,2,6.6-tetramethyl piperdine-1-sulfanyl (TEMPS)-acrylate;
- an ethylenically unsaturated disulfide monomer;
- an ethylenically unsaturated dithioester monomer, an ethylenically unsaturated dithiocarbamate monomer, an ethylenically unsaturated dithioester monomer, or an ethylenically unsaturated xanthate monomer unit;
- and
- 2) one or more other ethylenically unsaturated monomer units;
- and
- b) optionally one or more additives.
