Beschreibung
Zusammenfassung:	A bonding liquid dispersion comprising polyvinyl acetate, mixed stabilisers, a coalescing agent and polyvinyl alcohol which complies with British Standards 5270 and 4071 and is preferably water resistant. This dispersion can be used to strengthen gypsum plaster, cement and wood adhesive compositions and improve water and creep resistance. A process for preparing such a bonding liquid is also described and involves polymerisisng the vinyl acetate in the presence of the mixed stabilisers, and once the polymerisation is substantially complete, adding polyvinyl alcohol and a coalescing agent to the mixture.
