摘要: Abstract In this study, as a serial of our previous studies, polystyrene (PS) containing acetyl group (CH 3 CO ) was used raw material and condensation reaction performed in basic medium with aliphatic saturated unsaturated aldehydes. Synthesized modified polystyrenes (MPSs) were characterized using spectroscopic ( 1 H NMR IR) chemical analysis methods. Atomic force microscopy (AFM), has been to determine the microstructure PS, APS MPS crotonaldehyde, example. The thermal properties polymers investigated after crosslinking by ultraviolet (UV) irradiation. MPSs quantitatively estimated from amount insoluble polymer well change glass transition temperature. As result, crotonaldehyde cinnamaldehyde had higher than others due two double bonds their structure. films resistant corrosive mediums. After irradiation, water sorption decreased 0.65%.
