Bio-assimilation master batch composition, processes for producing polymeric bio-assimilating material therefrom, and products produced therefrom
A bio-assimilation master batch including a carrier resin, one or more transition metals, and one or more primary antioxidants is provided. The master batch may include one or more secondary antioxidants and one or more bioassimilation promoting additives. A process for producing polymeric bio-assimilating material including creating a master batch, mixing the master batch with a host polymer to form an end-use polymer mixture, and introducing the end-use polymer mixture to a polymer processing device to manufacture a polymer-based article. Products produced from a process for producing polymeric bio-assimilating material including creating a master batch, mixing the master batch with a host polymer to form an end-use polymer mixture, and introducing the end-use polymer mixture to a polymer processing device to manufacture a polymer-based article.

a. 4 wt % of manganese stearate;
b. 0.5 wt % pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate) as a primary anti-oxidant;
c. 0.5 wt % tris (2,4-di-tert.-butylphenyl) phosphite as a secondary anti-oxidant;
d. 3 wt % polycaprolactone as a bio-assimilation promoting additive;
e. 3 wt % ethylene vinyl acetate as a bio-assimilation promoting additive;
f. 89 wt % low density polyethylene, as a carrier resin; and
the master batch composition having a let down ratio in raw material of 1%.
2 . A master batch composition for an article requiring a functional life of approximately twenty-four months, consisting of:
