Abstract
Official abstract text for this publication.
A process for producing a fluorinated olefin/vinyl alcohol copolymer, which comprises emulsion polymerizing a fluorinated olefin and a vinyl ether in the presence of an aqueous medium and an emulsifier and converting the repeating units based on the vinyl ether to the vinyl alcohol.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for producing a fluorinated olefin/vinyl alcohol copolymer, comprising: (1): emulsion polymerizing a fluorinated olefin of formula (1) and a vinyl ether of formula (2) in an aqueous medium comprising an emulsifier to obtain a fluorinated olefin/vinyl ether copolymer, wherein the mass ratio of the vinyl ether of formula (2) to the aqueous medium is from 5/95 to 70/30: CF 2 ═CFX 1 (1) CH 2 ═CHOR 1 (2) wherein in formula (1), X 1 i…
