Saturated character of ethylene/octene thermoplastic elastomers demands an application of nonconventional methods of crosslinking connections between chains of molecules. These are organic peroxides, usually in the presence of coagents or an applicat

Radiation crosslinking of elastomers is an example of the modification of polymers by ionizing radiation. In practice, often parallel both traditional crosslinking (with peroxide) and radiation treatment is applied ( Bik et al., 2003 , Bik et al., 20

An introduction to problems of the working group at the European COST programme D-27 (Prebiotic Chemistry and Early Evolution) is presented. The neglected role of radiation chemistry in that field is discussed.

The mechanism of radiolysis of polymers can be recognized by product analysis and identification of reaction intermediates, followed by their determination. Among product analysis methods, the most appropriate is spectrophotometry. Due to the poor tr

Two-components blends, of compositions in a range from 100% of high density polyethylene (PE) to 100% of butadiene–styrene block copolymer (SBS) were investigated from the point of view of basic radiation chemistry and modifications of technologica

Application of diffuse reflectance spectrophotometry (DRS) in the investigation of stable and semi-stable products of radiolysis in solid state radiation chemistry creates the possibility of spectrophotometric measurements in the case of opaque objec

The alanine dosimeter made for evaluation by diffuse light reflection spectrophotometry (ALA/DRS) does not show the effect of orientation of crystals. Supposed deviation from random orientation has been investigated by EPR spectroscopy. EPR investiga

The article presents from the perspective of one hundred years the work of Maria Curie-Skłodowska, which in many cases was ahead of the state of knowledge of the time. It opened new horizons and for this reason we made many digressions. The fact of

Conditions for the observation of dry electron reactions are outlined. A new system for the investigation of dry electron reactions is proposed. It is the aqueous clathrate of tetrabutylammonium hydroxide or fluoride in which N 2 O also is matrix iso

X-ray analysis has been used to elucidate the structure of hydrates, especially of aqueous clathrates, but it has not given information on imperfections occuring in crystals. Other methods, sensitive to the disturbance of structural periodicity, have
