Abstract:
Disclosed herein is a process for producing polymers of an N-vinyl carboxamide, including the steps of flowing a reaction mixture containing an aqueous liquid containing at least one polymerisation initiator, N-vinyl carboxamide monomer or a monomer mixture containing N-vinyl carboxamide into a reactor system, and polymerising the monomer or monomer mixture to produce the polymer of a N-vinyl carboxamide. The polymers resulting therefrom may be hydrolysed to provide polymers containing vinyl amine units. Also disclosed herein is an apparatus suitable for producing the polymers.

Claim (Index 14):
An apparatus, comprising a reactor system suitable for producing a polymer of a N-vinyl carboxamide by polymerising an N-vinyl carboxamide monomer or a monomer mixture comprising N-vinyl carboxamide contained in an aqueous reaction mixture,\n wherein: the reactor system comprises a series of reactor units comprising a combination of at least one mixed flow reactor and at least one single pass tubular reactor, in which i) the at least one mixed flow reactor comprises at least one vessel comprising an internal mixer, an external mixer, or both, and ii) the at least one single pass tubular reactor comprises a tubular section disposed between two ends, at least one inlet and at least one outlet, in which the reactor system is arranged such that reaction mixture flows through the single pass tubular reactor only once; and the reactor system is provided in such a way that substantially none of the reaction mixture exits the single pass tubular reactor less than 0.5 of g mean residence time of the reaction mixture in the single pass tubular reactor.
