Представлено описание методов и алгоритмов, позволяющих проводить исследование кинетической неоднородности полимерных продуктов, получаемых в присутствии микрогетерогенных каталитических систем. Для случая интервального характера исходных экспериментальных данных, полученных результате проведенного гель-хроматографического анализа, проведена модификация метода решения обратной задачи формирован...

Constant temperature-constant pressure (NpT) molecular-dynamics computer simulations have been carried out for the united-atom model of a non-crosslinked (1,4) cis-polyisoprene (PI) melt confined between two amorphous, fully coordinated silica surfaces. The Lennard-Jones 12-6 potential was implemented to describe the polymer-silica interactions. The thickness H of the produced PI-silica film ha...

The “glass transition problem,” which refers to the spectacular change in dynamic properties of liquids cooled towards their glass transition, remains unsolved. The difficulty is that there are many properties associated with vitrification of a liquid, and these have interrelationships which complicate any analysis. Recently attention has been directed at the spatial heterogeneity of the dynami...

We introduce the use of a hydroborated polyisoprene (PIP) macroinitiator for the rapid surface-initiated growth of superhydrophobic polymethylene (PM) films. Rinsing of a dip-coated PIP film on a methyl-terminated surface atop silicon or gold substrates results in robustly bound, isolated PIP clusters. After hydroboration of the internal olefins, these clusters result in extremely rapid growth ...

For miscible blends of moderately entangled cis-polyisoprene (PI) and poly(p-tert-butyl styrene) (PtBS), viscoelastic and dielectric properties were examined over a wide range of temperature (T ) to discuss the thermo–rheological behavior of respective components. Because PI has the type-A dipole, whereas PtBS does not, the slow dielectric response of the blends was exclusively attributed to th...

A cis-1,4-polyisoprene-degrading bacterium (strain Kb2T) was isolated from foul water taken from the inside of a deteriorated automobile tyre found on a farmer's field in Westfalia, Germany. The strain was aerobic, Gram-positive, exhibited orange smooth and rough colonies on complex nutrient agar, produced elementary branching hyphae that fragmented into rod/coccus-like elements and showed chem...
