Název v původním jazyce

Effect of Styrene and Methyl Methacrylate Comonomers in Ethyl Acrylate/Methacrylic Acid Latex Particles Alkali-Swellability and Film Formation

Popis výsledku v původním jazyce

Series of emulsion copolymers were synthesized comprising methacrylic acid in the in constant level of 10 wt. % ethyl acrylate as a "soft" comonomer and different levels of methyl methacrylate or styrene as "hard" comonomers. It was shown that the extentof particle swedling and hydroplasticization was affected by the "hard" comonomer content and its polarity. The MFT results were found to be in good agreement with the titration curves with Zeta-potential measurements and with the flow behavior of the copolymer latices. As the hydroplasticization is based on the particle surface swelling by water it also is accorpanied by a strong increase in latex viscosity, this also being dependent on the comonomer polarity, Particle hydroplasticization affected physical-mechanical properties of pigmented coatings.
