“…Usually, the acrylic chains are substantially longer than the alkyd ones, and therefore most of the acrylic chains contain some alkyd grafted (i.e., ADG is high), whereas only a fraction of the alkyd is grafted to the acrylic polymer, namely, the majority of the alkyd is not grafted [38] (i.e., RDG is usually low). RDG can be increased by maintaining the alkyd resin and the acrylic polymer in close vicinity (hydrophobic resins give higher RDG than hydrophilic ones), using initiators that generate radicals active in hydrogen abstraction (e.g., tert-butyl hydroperoxide, TBHP/ascorbic acid, AsAc, which yields oxygen centered radicals and hydrophobic enough to readily enter into the polymer particles) [42], and using monomers of different reactivity with the double bonds of the alkyd resin (e.g., acrylates are more reactive than methacrylates) [31].…”
