Bioplastics - a sustainable solution?
Plastic is a product that has a wide range of applications, but the product also has a disadvantage - it is not degradable. It can be recycled and used for new purposes. The presentation includes the following aspects: typical applications of polymers, bioplastics, biodegradation, biorefining...
Morphology, crystalline features, and tensile properties of syndiotactic polypropylene blends
Syndiotactic polypropylene (sPP) was modified with ethylene–octene copolymer (EOC) and ethylene–propylene rubber (EPR), with test samples prepared in a twin-screw extruder and then injection-molded. The phase morphology, rheology, and thermal and tensile properties of the modified sPP were...

Physical extruder foaming of poly(lactic acid)processing and foam properties
The article describes extrusion foaming of poly(lactic acid) (PLA) using carbon dioxide in the supercritical state as foaming agent emphasizing the steps required to establish a stable extrusion process. Low melt strength of PLA plays a role in optimizing processing conditions. The tests included...
A method for estimating the fibre length in fibre-PLA composites
Wood pulp fibres are an important component of environmentally sound and renewable fibre-reinforced composite materials. The high aspect ratio of pulp fibres is an essential property with respect to the mechanical properties a given composite material can achieve. The length of pulp fibres is...
Nonisothermal melt crystallization kinetics of syndiotactic polypropylene/alumina nanocomposites
Nonisothermal melt crystallization kinetics of syndiotactic polypropylene (sPP)/alumina nanocomposites were investigated via differential scanning calorimetry. The addition of alumina nanoparticles significantly increases the number of nuclei and promotes the crystallization rate of sPP...
Morphology of syndiotactic polypropylene/alumina nanocomposites
The effect of the addition of 50 nm spherical alumina nanoparticles with hydrophilic or hydrophobic surfaces on the morphology of syndiotactic polypropylene (sPP) was investigated. The filler content in the nanocomposites was 3 wt%. Polarized Optical Microscopy and Small Angle Light Scattering (SALS...
