Abstract
A simple strategy was developed for the modification of linseed oil-based alkyd resin with glycidyl polyhedral oligomeric silsesquioxanes (GPOSS) to obtain a hybrid material. The incorporation of GPOSS into alkyd resin was done by simultaneous reactions between hydroxyl groups coming from ring-opened epoxides of GPOSS and partial glycerides and carboxylic acid groups of phthalic anhydride. The obtained hybrid material has significantly improved film properties and thermal stabilities compared to unmodified neat alkyd resin. Notably, the samples containing 5% GPOSS showed better film properties such as flexibility, adhesion, drying time, resistances to alkali, acid and water. Thus, this product can be used as an oil-based binder.
