| abstract | 1517067 Production of polyvinyl acetategrafted-PVA dispersions ANIC SpA 23 June 1976 [24 June 1975] 26003/76 Heading C3P An aqueous dispersion of polyvinyl acetate in which the polyvinyl acetate is grafted on to a polyvinyl alcohol, is prepared by polymerizing vinyl acetate in aqueous dispersion in the presence of (a) at least one peroxide and/or persulphate, (b) a reducing agent comprising at least one mono- and/or dicarboxylic acid, (c) an acetate and/or sulphate of an element of Group VIII of the Periodic Table, (d) a bicarbonate and/or an acetate of an alkali and/or alkaline earth metal and (e) polyvinyl alcohol or a partially esterified polyvinyl alcohol; component (d) being added throughout the polymerization. An optional additional component is a modifier which is an aldehyde with a boiling point under 70 C. or an ester of a butyl alcohol with a boiling point above 150 C. Specific examples of component (b) are formic acid, tartaric acid, maleic acid and oxalic acid. Preferred Group VIII elements for the salt of component (c) are Fe and Co. Specific optional modifiers are propionaldehyde, acetaldehyde, crotonaldehyde, butyraldehyde, and butyl glycolate. The dispersions are used as adhesives. |
