    摘要: 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.

    摘要: The present disclosure relates to a compound U comprising at least one urethane functional group, and its use as a fluidizing agent or fluidizing agent precursor in a process for preparing a polyamide article. The process comprises heating a composition comprising at least one polyamide PA and at least one compound U comprising at least one urethane functional group, at a temperature T, for a time t and at a pressure P, wherein the temperature T and the time t are such that CO2 is generated and the melt viscosity of the composition is decreased, in comparison with the melt viscosity of the composition without compound U, and recovering the article. The fluidizing agent can further enable the production of an article that has an unreduced density and/or in which the mean molar mass of the polymers of the composition is increased.
