Use in structural adhesives of aqueous polymer dispersions made by emulsion copolymerisation of styrene and diene in presence of protective colloid and in absence of emulsifier

摘要

Polymer dispersions or water-redispersible polymer powders for use in structural adhesive formulations are obtained by emulsion copolymerisation of vinylaromatic(s) and 1,3-diene(s) in presence of protective colloid(s) and in the absence of emulsifiers, optionally followed by drying the dispersion.
