Abstract:
The amino-terminated photo-sensitive copolymers (NH2-P(VM-co-AMPS)) were first prepared via a free radical polymerization. Then the graft copolymers (SPI-g-P(VM-co-AMPS)) were prepared by a graft reaction between the carboxylic acid groups of soy protein isolate (SPI) and the amino groups of NH2-P(VM-co-AMPS) using 1-(3-(dimethylamino) were characterized by FTIR and 1H NMR. The aqueous solution behavior were studied by transmission electron microscopy(TEM), dynamic light scattering (DLS), UV-vis spectroscopy, zeta potential. The results showed that SPI-g-P(VM-co-AMPS) could self-assemble into the spherical aggregates with the average size (Rh) of 105 nm. UV-vis spectra confirmed that the aggregates was photo-crosslinkable.
