Beneficial Micro Reactor Properties for Polyacrylate Formation

2 Beneficial Micro Reactor Properties for Polyacrylate Formation 

Micro mixers permit mixing times much below 1 s. Some multi-lamination micro mixers even approach sub-millisecond mixing [40]. Therefore, mixing can performed faster than most knovm reactions, including fast radical polymerizations. 

3 Polyacrylate Formation Investigated in Micro Reactors Organic synthesis 61 [OS 61] Radical polymerization of acrylates 

This reaction includes modified acrylates with or without addition of styrenes in combination with one or more initiators in a solvent [126], In an example, tetrahydrofuran was used as solvent and the polymer concentrations amounted to about 5.6 g Thus, the polymerization is carried out as solvent process. 

The ratio of monomer to initiator ranges from 1 1 to 10 1, and preferentially is set to 9 1 [126]. By setting initiator concentration, initiator type, residence time and temperature, the polymer molecular weight, conversion and solution viscosity are determined. The monomer is, e.g. acrylate-based with or without styrene. The pressure is regulated to be 2 x 10 -5 x 10 Pa in order to avoid solvent and monomer boiling.
