    Swelling of acrylic microgels in aliphatic ketones

  • Original language description

    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

    Rozustnost akrylátových mikrogelů v alifatických ketonech

  • Czech description

    Článek prezentuje výsledky v oblasti rozpustnosti ?OH funkcionalizovaných mikrogelů a alifatických ketonech. Mikrogely byly syntetizovány semikontinuální emulzní polymerací, MMA, BMA, HEMA, AMA. Byl zjištěna závislost rozpustnosti v závislosti na stupnizesítění mikrogelů. Dále byly mikrogely využity jako prekurzory sítí pro komerční akrylátové systémy. Bylo zjištěno, že mikrogely rozpuštěné v acetonu, nemají negativní vliv na vzhled ilmu, naopak zlepšují finální vlastnosti filmu a dobu vytvrzování.
