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.
