Claims18
A polyurethane elastomer composition comprising:
- a polyether carbonate polyol;
- an isocyanate compound;
- and
- a chain extender,
- wherein the polyether carbonate polyol comprises a copolymer obtained from polymerizing a polyether polyol, propylene oxide, and carbon dioxide, and is represented by [Chemical Formula 1] below,
- wherein x is an integer of 10 to 20, and y is an integer of 10 to 20,
- wherein the polyether polyol comprises one or more selected from the group consisting of a polypropylene glycol block copolymer, a polyethylene glycol block copolymer, a polytetramethylene ether glycol block copolymer, a block copolymer of ethylene oxide and propylene oxide, a butylene oxide polymer, and hyperbranched polyglycidol.
