Mechanical characteristics and water permeability of films on the basis of mixtures of LDPE PHB and PVA PHB depending on their composition were investigated. It was shown that the additive of PHB increments water permeability of a polymeric matrix, but at major dosage of PHB the permeability of films can be reduced because of ability of PHB to fix water. It was determined by DSC, polarization IRspectroscopy, WAXS and SAXSexperiments that there is a connection between structural architecture of films at crystalline ( or at molecular ) level with water permeability and mechanical performances. It was shown that the decreasing of strength of films occurs at concentration PHB above than 10 % (for LDPE PHB mixtures ) and above than 20 % (for PVA PHB mixtures). |
