High demands and diverse
applications of plastic materials had contributed immensely to the
social-economic growth of the nations especially in the packaging industry.
However, plastics have been a major contributor to the world’s present
garbage problems especially from the packaging sector of the industry. The
menace was traced to non-degradable characteristics of LDPE and HDPP resins
often used in the productions, hence, the need for biodegradable polymer
blends.;l Co-polymer from Cassava (Manihort Species) starch with glycerol,
vinegar and water was formulated to produce slurry, which was heated to
about 1000c to form gel, dried to about 12% moisture. The resulting chips
were  weighed in the ratios of 1:0,
1:3, 1:1, 3:1, 0:1 (wt/wt %)  to pure
low density polyethylene (LDPE) resins. Each formulation of mixture was
extruded at 1600C to produce polymer blends (plastics) in batches. The
samples were chipped into same dimensions of 2.0mm thickness, 15.00mm width
and 30.00mm and characterized. The mechanical properties of the polymer
blends were found to decrease as the Copolymer increased. The best Young
modulus was achieved with pure LDPE extrudate having 0.45±0.005 (109N/m,Gpa)
and the least in the pure copolymer 0.11±0.005 (109N/m,Gpa). The homogenous
dope exhibited compatibility of cassava starch with polyethylene and it took
up to 72 hr for each of the samples to cure completely.
