چکیده
A native potato starch was modififi ed with vinyl acetate by graft polymerization in alkaline medium pH 10 the mode of temperature change from 70 to 80°C for 4 hours. The initiator process ammonium persulfate (NH ) 2 S O 8 . conversion 91,5%. chemical structure copolymer (Starch:Vinyl acetate) confifi rmed IR-spectroscopy. Composite materials and triethyl citrate tensile strength 24 MPa were obtained. Under natural environmental conditions, undergo biodegradation 96% 28 days.

Graft Polymerization of Vinyl Acetate onto Starch. Saponification to Starch-g-Poly(vinyl Alcohol)
Graft polymerizations of vinyl acetate onto granular corn starch were initiated by cobalt-60 irradiation of starch-monomer-water mixtures. and ungrafted poly(vinyl acetate) was separated from the graft copolymer by benzene extraction. Conversions of monomer to polymer were quantitative at a radiation dose of 1.0 IvIrad. However, over half of the polymer was present as ungrafted poly(vinyl aceta...
