✦ Synopsis

The viscoelastic behavior of three alkyd ceramers was studied using dynamic mechanical thermal analysis (DMTA). A commercial product was compared to model alkyds. The model alkyds were prepared from phthalic anhydride, glycerol, and linseed or sunflower seed oil. Three sol-gel precursors, titanium tetra-i-propoxide, titanium di-i-propoxide diacetylacetonate, and zirconium tera-n-propoxide were investigated. The alkyd ceramers were evaluated as a function of both alkyd type and a sol-gel precursor content. The viscoelastic data showed that both EЈ and T g were affected by sol-gel precursor content. Both the crosslink density and T g demonstrated a minimum at low sol-gel precursor contents. After this minimum, both the crosslink density and the T g increased substantially.

The storage modulus (EЈ) and loss modulus (EЉ) of Japanese lacquer films were measured over a temperature range of Ϫ150 to 400°C. Three relaxation processes labeled ␣, ␤, and ␥ were detected at 80, Ϫ60, and Ϫ140°C, and their apparent activation energies (⌬E) were 63-91, 13, and 9 kcal/mol, respectiv
