ABSTRACT:
Aldehyde functional polymers having a molecular weight of about 500 to 50,000 and containing aldehyde functional groups at both ends and/or on side chains of the molecule are produced by subjecting some of the double bonds in a high polymer containing olefinically unsaturated double bonds to ozone-decomposition by ozone-containing gas and reducing the ozone-decomposition products by means of a trivalent phosphorus compound as a reducing agent into substantially only aldehyde functional groups.
