摘要

Rubber seed oil alkyd was post-polymerized with styrene monomer at ratios of 1:2, 1:4, 1:6, 1:8, and 1:10 at 100°C for 3 h (samples i - v) and 6 h (samples A - B), to obtain two sets of styrenated alkyds. The styrenated alkyds and the rubber seed oil alkyd were all characterized and evaluated by standard methods, for their physico-chemical properties, drying schedule and chemical resistance. All the resins showed good properties. However, the styrenated alkyds gave a faster drying time, even in the absence of a drier. Unlike the unstyrenated alkyd which is only resistance to water, brine and acidic media, the styrenated alkyds were also resistant to alkali. The styrenated alkyds prepared over a period of 6 h gave shorter drying time than those prepared in 3 h, irrespective of the alkyd - styrene ratios.
