The invention relates to a three-phase hydrolytic polymerization process for nylon 6. The process includes the steps of raw material preparing, pre-early polymerization reaction, early polymerization reaction, later polymerization reaction and cooling and slicing. The three-phase hydrolytic polymerization ...
Conversion–time data are the basis for the calculation of reactor performance. The ratio between the reaction time required for obtaining a certain conversion and the time constant of the reaction is a characteristic dimensionless number of the reaction, namely the Damköhler number56 Da, which en...
Polymerization reaction measurement is crucial to produce material that meets requirements ✔ Immediate understanding ✔ Accurate & reproducible ✔ Improved safety
Constant composition recycle of nylon 6 polymerization wash water A process for preparing polyamides from amide monomers in a reaction vessel where a portion of the monomers remain unreacted or form oligomers as an extractable fraction includes extracting from the polyamide unreacted amide monomers and....

small molecules like H2O, CO, NH3, are eliminated during polymerization (step growth polymerization). Generally, organic compounds containing bifunctional groups, such as idols, dials, diamines and dicarboxylic acids, undergo this type of polymerization reaction. For example, preparation of nylon -6,...
