خلاصه مقاله:
Novel poly (acrylic acid) microgels were prepared by using multi functional cross-linkers and acrylic acid (AA) via precipitation polymerization. The properties of these microparticles exhibit a strong dependence on the cross-linker structure. Capability of solvent absorbency and visocity enhancement demonstrated that the structure of samples depend very strongly number of functional and number of hydrophobic group of cross-linkers. The gel content values indicate thatuncross-linked oligomers (i.e., low soluble fraction) are diminished as the numberof functionality is increased. The glass transition temperature is closely depend on cross-linker density
