| Abstract: | Polysiloxane-g-(styrene-co-butyl acrylate) copolymers with different architectures (four-armed star and brush) were synthesized and introduced into an alkydic resin in order to improve the flow properties and formulate new systems for painting applications. The viscoelastic properties of the alkydic resin as compared with the additives samples were investigated at different temperatures in the range of 0°C to 80°C. The experimental data showed that a small quantity of polymers with controlled architectures determines changes in the rheological behaviour of the resin solutions, the brush copolymer being more efficient as a viscosity improver. |
