Resumo
Hydrocarbon polymers, as PP, made from cheap petrochemical feedstock are important in
many branches of industry. However, they have an undesirable influence on the environment
and cause problems due to waste deposition and utilization. Polymeric materials composites
account for an estimated from 20 to 30% of total volume of solid waste disposed. Thus, there
is a tendency to substitute such polymers by those ones that undergo biodegradable processes.
Polypropylene (PP) is a commodity, with high melting point, high chemical resistance, low
density, with a balance between physical and mechanical properties and easy processing at
low cost. Nevertheless, PP shows limitations for some special applications in automotive
industry and civil construction. In order to minimize this deficiency, related to rheological
behavior of polymer melt, especially referring to viscosity in processing temperature, a 50%
mixture with HMSPP (High melt Strength Polypropylene) was used. PP/HMSPP was
blended with 10, 15, 30 and 50% of natural (sugarcane bagasse) and synthetic polymers
(PHB and PLA) aiming to partially biodegradable materials. The admixtures were subjected
to gamma-irradiation at 50, 100, 150 and 200 kGy and then further assessed by mechanical
tests in order to evaluate their degradability.
