Abstract: The invention relates to a papermaking agent composition, preferably in powder form, which comprises a water-soluble polymer, which comprises 21-30 mol-% of vinylamine units and has an average molecular weight of at least 1 000 000 Da. The invention relates also to a method for treating of fibre stock in manufacture of paper, board or the like, where a thick fibre stock is obtained, it is diluted to a thin fibre stock having a consistency
Abstract translation: 本发明涉及一种造纸剂组合物，优选粉末形式，其包含水溶性聚合物，其包含21-30摩尔％的乙烯胺单元并且具有至少1 000 000Da的平均分子量。 本发明还涉及在纸，纸板等的制造中处理纤维原料的方法，其中获得厚纤维原料，通过加入水稀释成稠度<3％的薄纤维原料，以及 将纤维原料排出并形成连续的纤维网。 将造纸剂组合物加入粗纤维原料或稀纤维中。
