Polietylen liniowy małej gęstości

2002

Artykuł o charakterze przeglądowym dotyczy jednego z gatunków polietylenu, tj. liniowego polietylenu małej gęstości (PE-LLD) stanowiącego kopolimer etylenu z niewielką ilością (kilku %) wyższej l-olefiny otrzymywany metodą polimeryzacji koordynacyjnej z udziałem metaloorganicznych układów katalitycznych. Omówiono wpływ typu katalizatora, w szczególności nowoczesnych układów metalocenowych, na aktywność w kopolimeryzacji i efektywność wbudowania komonomeru do łańcucha polietylenowego. Przedstawiono przemysłowe metody otrzymywania PE-LLD oraz charakterystykę tego produktu na tle znanych gatunków polietylenu - PE-LD i PE-HD. Omówiono także wpływ budowy chemicznej PE-LLD na jego podstawowe właś…

1986

Ultimate tensile properties and dart impact behaviour of coextruded films of LDPE and LLDPE were compared with those of films made from blends of the same resins. The effect of composition and of both blow up ratio and axial draw ratio of the blowing process on film properties was explored. The results indicate that, at least for semicompatible systems like that considered here, films made from blends and coextruded ones have mechanical properties very close to each other. Die Festigkeitseigenschaf ten und das Verhalten beim Kugelfalltest von coextrudiertcn Filmen aus LDPE und LLDPE wurden mit den entsprechenden Eigenschaften von aus Mischungen dieser Polymere hergestellten Filmen vergliche…

Spatial differences and temporal changes in illicit drug use in Europe quantified by wastewater analysis

2014

Aims To perform wastewater analyses to assess spatial differences and temporal changes of illicit drug use in a large European population. Design Analyses of raw wastewater over a 1-week period in 2012 and 2013. Setting and Participants Catchment areas of wastewater treatment plants (WWTPs) across Europe, as follows: 2012: 25 WWTPs in 11 countries (23 cities, total population 11.50 million); 2013: 47 WWTPs in 21 countries (42 cities, total population 24.74 million). Measurements Excretion products of five illicit drugs (cocaine, amphetamine, ecstasy, methamphetamine, cannabis) were quantified in wastewater samples using methods based on liquid chromatography coupled to mass spectrom…
