INJECTION MOLDED BIODEGRADABLE STARCH POLYMER COMPOSITE

摘要

An injection moldable biodegradable plastic formed of corn starch and low-density polyethylene. Ethylene acrylic acid co-polymer can be included in proportions ranging from 0-10 % by weight, and sodium hydroxide can be utilized to neutralize the acidic portions of the ethylene acrylic acid co-polymer. When no ethylene acrylic acid co-polymer is utilized, glycerol is added. To improve injection molding characteristics, the ethylene acrylic acid co-polymer and polyethylene are premixed before the addition of corn starch.
