Abstract
Official abstract text for this publication.
The present invention relates to a polyester or polyurethane polymer comprising a biomass-derived 1,3-cyclopentanediol monomer, and a method for preparing same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymer compound represented by Chemical Formula 1 comprising a biomass-derived 1,3-cyclopentanediol monomer: wherein R is a compound of Chemical Formula 2 or Chemical Formula 3, wherein * is a linking position, and a is an integer of 1 to 30, b is an integer of 1 to 30, and c is an integer of 1 to 30. 2. The polymer compound of claim 1 , wherein the 1,3-cyclopentanediol included in Chemical Formula 1 is a compound prepared from a biomass-derived furfuryl alcohol. 3. The polymer compound of claim 1 , wherein the polymer compound of Chemical Formula 1 is a random copolymer of a 1,3-cyclopentanediol monomer, a terephthalic acid monomer, and a succinic anhydride monomer, or a random copolymer of a 1,3-cyclopentanediol monomer, a terephthalic acid monomer, and a 2,5-furandicarboxylic acid monomer. 4. The polymer compound of claim 1 , wherein the polymer compound of Chemical Formula 1 has a molecular weight of 10000 to 70000. 5. The polymer compound of claim 1 , wherein the polymer compound of Chemical Formula 1 has transparency of 80% to 100% according to ASTM D1003, a flexural strength of 120 N to 200 N according to ASTM D-790, and a tensile strength of 100 MPa to 200 MPa according to ASTM D-638.
