PREPARATION AND CHARACTERIZATION OF POLYMERIC DISPERSANTS BASED ON VEGETABLE OILS FOR PRINTING INK APPLICATION
Mohamed Ahmed Abdelaziz;
Abstract
ABSTRACT
In this work, novel vegetable oil-based polymers were prepared by epoxidation of soybean oil (SBO), castor oil (CO) and Linseed oil (LO) followed by ring opening reaction of the epoxidized oils with polyether amine and polypropylene glycol. Castor oil was reacted with maleic anhydride to give maleated castor oil which reacted with polypropylene glycol.
The prepared polymers were characterized by FTIR and GPC. The properties of vegetable oils and epoxidized vegetable oils (EVO) were studied. The prepared polymers were employed as novel polymeric dispersants for pigment dispersion in solvent based printing ink application. The mechanical and optical properties of prepared ink formulations were studied. The net technical properties of the new ink formulations are relatively comparable to the printing ink formulationformulated by commercial polymeric dispersant. The polymeric dispersant 2 (PD2) and polymeric dispersant 4 (PD4) gave the best optical and mechanical properties among the prepared polymers for cyan ink.Polymeric dispersant 7 (PD7) gives the best optical and mechanical results among the prepared polymers for magenta ink.
