This work reports on the development of polylactide (PLA) and polycarbonate (PC) blends with different compatibilizers enhanced toughness. Since both polymers are immiscible, two types tested: petrochemical-based copolymers Xibond 160 920 maleic anhydride epoxy groups, respectively, natural-based same functionalities, namely maleinized linseed oil (MLO) and, epoxidized (ELO). Mechanical, therma...

Abstract A case of a bridge composite girder is analysed. According to EC4 rules, its cross section coinciding into class 1 and should be able resist the design moment in ULS. But after tracking loading history with gradually increasing live load up level, it established, that an early web instability exists before ends. This effect contradicts some code settings considered as warning designers...

With the development of self-healing materials and increasing demands from complicated application environment, underwater is attracting more attention. However, until now, effects different dynamic chain extender water molecular on polyurethanes have not been investigated yet. In this work, we synthesized two types with 2,4-pentanedione dioxime (DMG) bis(4-hydroxyphenyl) disulfide (HPS) as ext...

The results of kinetic investigations the orthodichlorbenzene and orthoxylene sorption by high density polyethylene specimens different thickness for 35 days are presented. It is shown that solvents in swelling polymer its plasticization, which expressed changes mechanical characteristics such as ultimate strength, deformation to failure, Young's modulus.

Abstract A process was developed combining two natural-based products to obtain bio-based films. Industrial cellulose pulp dissolved and mixed with epoxidized soybean oil (ESBO), which acts as an internal plasticizer. distillable recyclable ionic liquid-based solvent used dissolve the cellulose. Appropriate distribution of cellulose/ESBO solution on glass surfaces careful regeneration enabled d...
