Synthesis of Glycidyl Methacrylate-Acrylic acid Copolymer Via ModifiedMicroemulsion Polymerization and Using It As Textile Pigment Printing Binder

摘要

Copolymerization of glycidyl methacrylate (GMA) and acrylic acid (AAC) was carried out via modified microemulsion polymerization process for textile pigment printing. Sodium dodecyl sulfate and Potassium persulfate/glucose were used as emulsifier and redox initiator, respectively. The prepared micro emulsion copolymer was characterized via spectroscopic measurements, FT-IR and transmission electron microscope (TEM), in addition to thermal analysis. Effects of polymerization parameters, such as monomer content ratio, initiator and emulsifier concentration on average particle size and size distribution have been studied. The prepared copolymer latex showed high performance physico-mechanical properties in addition TEM analysis showed that the polymer latex nano particle within rang of 35 – 74 nm. The study involved the application of the prepared micro-emulsion co-polymer as binder for pigment printing process onto cotton fabric by using a flat screen technique and the prints were dried and thermal cured. The optimum curing conditions were determined, color strength and fastness properties of pigment printed areas to light, washing, perspiration and crocking were evaluated. In addition stiffness of the prints was also determined
