摘要： The invention relates to a process for manufacturing wet strength resins, which process comprises a polyamide reactor (11) for amidation, an EHH reactor (12) for epihalohydrin addition, a maturing tank (15) for maturing, a ring-closure and cross-linking reactor (16) for polymerization, and in the process a reaction mixture containing at least EHH and at least polyaminoamide epihalohydrin adduct is manufactured. The process further comprises between the maturing tank (15) and the ring-closure and cross-linking reactor (16) a membrane unit (20) comprising a membrane by dividing the reaction mixture stream from the membrane unit (20) into two streams: a permeate stream (202) comprising un-reacted epi-halohydrin and a reject stream (201) comprising EHH/PAIM adduct guided to the ring-closure and cross-linking reactor (16).
