Effect of Acetate Group Content in Ethylene-Vinyl Acetate Copolymer on Properties of Composite Based on Low Density Polyethylene and Polyamide-6

Table 3

Assessment of biodeterioration of polymer blends for various incubation times where 0 point: lack of microorganisms on the surface of sample; 1 point: traces of microorganisms (less than 10% of the coating covered by fungal growth); 2 points: insignificant growth (10% to 30% of the coating covered by fungal growth); 3 points: significant growth of microbial colonies (30–60% of the coating covered by fungal growth).
