Natural Oil-Based Alkyd-Acrylic Copolymers: New Candidates for Barrier Materials
Tóm tắt
The feasibility of using alkyd-acrylic copolymers as a barrier material was studied. Copolymers of tall oil fatty acid or rapeseed oil-based alkyd resin and polyacrylates were synthesized and films of these copolymers were prepared. Nuclear magnetic resonance spectroscopy revealed that after copolymerization the proportion of double bonds in alkyd resin was diminished due to grafting reactions. The mechanical properties, such as strength and flexibility, of the copolymer films were tested, and the performance of the films as water, oil, and oxygen barrier was evaluated. An increased amount of alkyd resin made the films more brittle and increased their oxygen permeability, however, at the same time their hydrophobicity was increased.
