Title:
VINYL ALCOHOL POLYMER AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/034906
Kind Code:
A1
Abstract:
The present invention provides a vinyl alcohol polymer that has comparable properties to a vinyl alcohol polymer derived from petroleum alone. Thus, the present invention contributes to conservation of oil resources and suppression of carbon dioxide emissions in the production process, in the case of using poly(vinyl alcohol) (PVA). The present invention pertains to a vinyl alcohol polymer (X), said vinyl alcohol polymer (X) being obtained by polymerizing a vegetable-origin vinyl ester monomer (A) with a petroleum-origin vinyl ester monomer (B) followed by saponification, wherein the molar ratio (A)/(B) is from 5/95 to 100/0.
