Definitions
- the invention relates to redispersible tackifier powders and adhesives which contain redispersible tackifier powders in powder form or in the form of their aqueous redispersion.
- the use as an adhesive is an important area of application for polymers, for example homopolymers or copolymers of vinyl esters, (meth) acrylic acid esters or styrene.
- An example of this is the use of vinyl acetate / ethylene copolymers as floor adhesives (EP-A 23360, US-A 4322330).
- EP-A 620243 describes the use of vinyl ester-acrylic acid ester copolymers as pressure-sensitive adhesives or floor adhesives.
- DE-A 3737630 (US-A 4975481) relates to contact adhesives based on ethylene-vinyl acetate copolymers.
- EP-A 17986 discloses pressure sensitive adhesives based on acrylic ester / vinyl acetate / ethylene copolymers.
