Ageing and stabilization polymers is a major part of materials science. Aging of polymers defined as a set of chemical and physical transformations, leads to the loss of their set the desired properties. The main role in these transformations belong to chemical processes of degradation and crosslinking of macromolecules. Processes decomposition and structuring polymer conjugates include radical...

BACKGROUND Polypropylene mesh used as a mid-urethral sling is associated with severe clinical complications in a significant minority of patients. Current in vitro mechanical testing shows that polypropylene responds inadequately to mechanical distension and is also poor at supporting cell proliferation. AIMS AND OBJECTIVES Our objective therefore is to produce materials with more appropriate...

The possibility of applying membrane distillation to support the fermentation process was investigated. The capillary polypropylene membranes were assembled in the membrane modules. The studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. The performance o...

Abstract This paper is investigated the effect of impregnation of the high modulus polypropylene shear thickening fluid. Fluid using silica nanoparticles dispersed in polyethylene glycol in both 42% and 44% has been achieved. The penetration tests conducted in this study is in accordance with NIJ 0101-04. The results are evinced that the penetration resistance is improved by impregnation of ...
