Title:
METHOD FOR PRODUCING CHEMICALLY RECYCLABLE POLY(VINYL ALCOHOL) COPOLYMER THROUGH RING-OPENING METATHESIS POLYMERIZATION OF CYCLOHEXENE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2023/200186
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a chemically recyclable polyvinyl alcohol copolymer through ring-opening metathesis polymerization of cyclohexene derivatives, wherein the ring strain energy of cyclohexene monomers is increased using trans-fused cyclic carbonate groups to perform ring-opening metathesis polymerization (ROMP) while efficiently controlling same to produce a polyvinyl alcohol copolymer with a well-defined structure of 1,2-diol per six carbon atoms and exhibiting high hydrolytic stability, excellent oxygen protective properties, and processability. In addition, the polyvinyl alcohol copolymer can be chemically recycled into 1,2-diol containing cyclohexene through the ring-closure depolymerization of the polyvinyl alcohol polymer, and useful compounds, including industrially useful α,ω-dialdehyde compounds, can be produced by chemically cleaving 1,2-diol groups.
