Abstract
The invention relates to an intermediate composition in form of an aqueous solution, having a dry solids content of 30-65 weight-%, for manufacture of a polyamidoamine epihalohydrin resin. The intermediate composition comprises a regulating acid, and 30-60 weight-%, calculated from the total weight of the intermediate composition, of a polyamidoamine derivative having covalently bound epihalohydrin groups and covalently bound azetidinium groups, wherein the intermediate composition comprises derivative bound halogen in an amount of ≤90 g/kg, calculated from the dry solids.
