Abstract
The invention relates to the use of protective-colloid-stabilized vinyl ester/ethylene copolymers in the form of polymer powder as low-profile-additives (LPAs).
Claims17
A radically crosslinkable polymer composition comprising one or more radically crosslinkable polymers, one or more ethylenically unsaturated monomers (reactive monomers) and optionally initiators, optionally fillers, and optionally further additions, wherein
- additionally one or more protective colloid-stabilized vinyl ester-ethylene copolymers in the form of polymer powder are present.
A process for producing a radically crosslinkable polymer composition, comprising mixing one or more radically crosslinkable polymers, one or more ethylenically unsaturated monomers (reactive monomers) and optionally initiators, optionally fillers, optionally reinforcing materials, and optionally further additives or additions, wherein
- additionally one or more protective colloid-stabilized vinyl ester-ethylene copolymers in the form of polymer powder are admixed.
