Abstract: A continuous process for the preparation of polyoxazolines comprises mixing monomers, an initiator, and optionally an additive, feeding the mixture into at least one tubular reactor segment with a feed side and an outlet side, and polymerizing the mixture to form the polyoxazolines. A tubular reactor segment comprises a mixer for forming a mixture comprising monomers, an initiator, an additive, a terminating agent, and/or a functionalizing agent, at least first and second tubular reactor segments, and addition devices for the first and second tubular reactor segments.
