The mechanical properties of the prepared polymers would be also examined. The prepared samples were applied as a textile pigment printing binder and tested their heat and mechanical fastness performance.Finally in group (V) the best terpolymer which crosslinked using the best crosslinker systems to achieve the best performance of the pigment printing binder.
It was found that AGE crosslinker improved the tensile strength of the ethyl acrylate polymer; in another hand AMA crosslinker improved the elongation of ethyl acrylate polymer.
Ethyl acrylate crosslinked by NMA had the highest weight average molecular weight than ethyl acrylate crosslinked by either AGE or AMA.
Ethyl acrylate polymer crosslinked by either AGE or AMA minimized the stiffening in the handle of the printed textile, increased color yield, increased the viscosity of the pigment printing paste so the consumption of thickeners would be decreased and finally had good heat and mechanical fastness properties.
group (III) study the effect of methyl methacrylate on methyl methacrylate/ethyl acrylate copolymers, it was found that methyl methacrylate improved the tensile strength and viscosity of the ethyl acrylate polymer but the elongation of the prepared copolymer decreased.
The heat and mechanical fastness properties of the printed samples showed that methyl methacrylate/ethyl acrylate copolymer had higher durability, sublimation and rubbing fastness than the ethyl acrylate homopolymer, although methyl methacrylate/ethyl acrylate copolymer maximize stiffening in the handle of the printed textile.
group (IV) study the effect of addition the soft monomer 2-ethyl hexyl acrylate on methyl methacrylate/ ethyl acrylate copolymer to improve the elongation and Tg as well as minimize stiffening in handle of the printed samples.
Finally in group (V), it was found that the best terpolymer performance can be obtained from 10% methyl methacrylate/ 10% 2-ethyl hexyl acrylate/ 80% ethyl acrylate terpolymer in presence of 1% of either AGE or AMA.
