Interpenetrating polymer networks of uralkyd resin based on hydrogenated castor oil and poly(butyl acrylate)

摘要

Semi- and full-interpenetrating polymer networks (IPNs) of uralkyd (UA) resin based on hydrogenated castor oil and poly(butyl acrylate) (PBA) were prepared by the sequential mode of synthesis. These IPNs were characterized for their resistance to thermal behavior, swelling (%), and mechanical properties. The morphology of the IPNs was studied by scanning electron microscopy (SEM). The effect of the variations of the blend ratios on the above-mentioned properties was examined. The mechanical properties significantly enhanced by increasing UA component in the blend. Full-IPNs exhibited higher apparent densities, mechanical properties, and thermal stability than the corresponding semi-IPNs. [References: 21]
