Název v původním jazyce

Swelling of acrylic microgels in aliphatic ketones

Popis výsledku v původním jazyce

The paper deals with the swelling behaviour of hydroxyl-functionalised microgels in the presence of aliphatic ketones. The copolymer microgels with different cross-linking densities were synthesized by the semi-batch emulsion copolymerisation of methyl methacrylate, butyl methacrylate, 2-hydroxyethyl methacrylate and allyl methacrylate. The extent of microgel particles swelling was evaluated using the dynamic light scattering, the potentiometric titration of accessible hydroxyl groups and the solvent-uptake measurements. It was found that the swelling ability of microgels decreased with growing degree of cross-linking. Microgels comprising copolymerised butyl methacrylate swelled less in utilised aliphatic ketones than microgels without this comonomer.Among all the investigated solvents, acetone was found to be the strongest solvent, while 5-methyl-2-hexanone (methyl isopentyl ketone) was shown to be the weakest one. Further, the microgels were investigated as reactive network precurs
