COPOLYMER, AQUEOUS SOLUTION COMPRISING THE COPOLYMER AND METHOD FOR REDUCING NEGATIVE EFFECTS OF NATURAL PITCH AND ADHESIVE CONTAMINANTS IN BOTH PULPING AND PAPERMAKING OPERATIONS

摘要

The present invention relates to a copolymer comprising at least one hydrophilic monomer; at least one hydrophobic monomer and at least 10% by weight of methyl styrene, particularly suitable to be used as detackifying agent for reducing negative effects caused by natural pitch and/or adhesive contaminants in both pulping and papermaking operations.
