Investigation of the synthesized acrylic terpolymers (MMA, n-BA, AA) Paint properties

Three series (A,B and C) of acrylic terpolymers: methylmethacrylate( MMA,50 wt%) n-butylacrylate( n- BA,40-50 wt%) and 0-10 wt% acrylic acid(AA)/or acrylonitrile(AN) were synthesized in toluene in the same condition. Adhesion, hardness, bending and impact resistance of the paint films, viscosity and drying time of the resins were measured according to ASTM tests and compared with the paint which we made of it asreferences. Comparison of the result showed that using 3 wt%AA could be preferred in the feed compositions. The paint films adhesion, hardness and toughness were increased to reach those of the reference sample using 3 wt% AA and by decreasing the concentration of MMA to 45 wt%.
