The invention relates to coating compositions having anti-adhesion and dirt repellency properties, these compositions being admixed as additive with from 0.1 to 10% by weight, based on the solids content of the coating composition, of a branched polymer which possesses a weight-average molecular weight of from 2000 to 200,000 and comprises a polymeric base molecule and also polydiorganosiloxane side chains which are bonded covalently to the base molecule via Si-C bonds, have a weight-average molecular weight of between 1000 and 30,000, and whose fraction of the total weight of the branched polymer is from 5 to 25% by weight. The present invention further relates to polymeric moulding compounds having anti-adhesion and dirt repellency properties, to which this branched polymer is added as additive in an amount of from 0.1 to 10% by weight, based on the total weight of the polymeric moulding compounds. The invention additionally relates to the use of the branched polymers as additives for coating compositions and polymeric moulding compounds.
