USE OF AMPHIPHILIC POLYMERS OR COPOLYMERS FOR SURFACE MODIFICATION OF REACTIVE INORGANIC FILLERS

摘要

Surface-modified fillers are described characterized by the fact that the fillers represent reactive inorganic fillers and the modifying agent represents an amphiphilic aminoplastic-ether polymer or copolymer of the structural type in which: Z denotes the same or different aminoplastic central units based on melamine-formaldehyde or urea-formaldehyde derivatives; n=10 to 500; R denotes the group -[O-CH₂-CH₂]_mO-S in which m=5 to 500 and S represents a substituted or unsubstituted alkyl, aryl, alkaryl or aralkyl group.
