The present invention relates to covalent adaptable networks (CANs) having exchangeable crosslinks which are able to undergo repeated covalent bond reshuffling through photo-activation at ambient temperatures. The invention provides covalent adaptable network forming compositions as well as methods of forming, remolding and recycling the CANs of the invention.

The present invention relates to a multilayered flooring decorative material comprising a first foam layer and a second foam layer, wherein the first foam layer is formed by foaming a foam layer composition, the second foam layer is formed by impregnating a fiberglass substrate with a foam layer composition, and the foam layer composition comprises a polyvinyl chloride resin, a plasticizer, a filler, a heat-resistant stabilizer, and a foam stabilizer.

The present invention provides an adhesive composition that exhibits excellent adhesive force, and can be easily separated by photocuring during a peeling step, in which foaming and lifting are not generated even after a high temperature process.
