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.
