资源简介：
The invention relates to a strength agent for paper， board or the like. The strength agent comprises a first component， which is refined cellulosic fibres having a refining level of >70 °SR， and a second component， which is a synthetic cationic polymer having a charge density of 0.1 – 2.5 meq/g， determined at pH 2.7， and an average molecular weight of > 300 000 g/mol. The invention relates also to a use of the strength agent and to a method for increasing strength properties of paper， board or the like.
