Abstract
The paper reviews recent studies concerning pectic acids or polygalact uronic acids in suspensions of mechanical pulps produced from Norway s pruce. Pectic acids dissolve from fibers to an aqueous phase in alkali ne conditions such as alkaline peroxide bleaching. They have a low mol ar mass and a high negative charge density. Pectic acids can have mani fold effects on papermaking including reacting with cationic polyelect rolytes and Ca2+ ions.
