WATER-REDISPERSIBLE POLYMER POWDER COMPRISING A TRIESTER

摘要

The present invention relates to a water-redispersible polymer powder comprising a water-insoluble polymer and a triester, wherein the triester is a triester of glycerol with a C1-to C5-carboxylic acid and/or a triester of a C1-to C5 -alcohol with a tricarboxylic acid. Furthermore, processes to make said water- redispersible polymer powder are disclosed. One process comprises the making of a powder i) comprising the triester and a water-soluble polymer, wherein the powder i) is mixed with a polymer powder PP comprising a water- insoluble polymer. The intermediate powder i) is claimed as well. The polymer powder of the invention can be used in powder adhesives, wallpaper adhesives or dry mortars.
