资源简介：
The invention relates to a dry strength composition for manufacture of paper， board or the like. The dry strength composition comprises， as a mixture， at least one anionically derivatized polysaccharide， and cationic starch having an amylopectin content > 80 weight-%. The anionically derivatized polysaccharide and the cationic starch provide the composition with a charge density in the range of 0.1 — 1.5 meq/g， when measured at pH 2.8， and -0.1 — -3 meq/g， preferably -0.3 — -2.5 meq/g， more preferably -0.5 — -2.0 meq/g， when measured as an aqueous solution， at pH 7.0. The invention relates also to a use of the said composition and to a method for manufacturing paper， board or the like.
