Linseed ? a natural source of health and beauty

Lech BARTKOWSKI ? Institute of Natural Fibres and Medicinal Plants, Poznań, Poland

Please cite as: CHEMIK 2013, 67, 3, 186-191 The history of flax (linum) dates back about 8,000 years B.C. At those times linen served  s threads for sewing skins together or as a string; later on a man learned how to weave  lothes. As time passed by, ancient people became true masters in this craft, laying  oundations for development of the textile industry. Today we can admire the samples of...

Sorbitol and cellulose derivatives as gelling agents

Małgorzata JAWORSKA, Otmar VOGT ? Institute of Chemistry and Organic Technology, Cracow University of Technology, Cracow, Poland Abstract: Gels are the substances with great significance in food industry, pharmaceuticals and cosmetics production as well as in construction chemistry. To form an appropriate consistence of chemical reparations is extremely important for their application properties. A significant difficulty in obtaining gel structure lies in the diversified properties (hydrophobic and hydrophilic) of the ngredients in the preparation. Thus the role of...

Sweetness covert in polymers

Anna MIELAŃCZYK, Dorota NEUGEBAUER ? Department of Physical Chemistry and Technology of Polymers, Faculty of Chemistry, Silesian University of Technology, Gliwice, Poland Abstract: This article is devoted to carbohydrates utilization, in particular acting as initiators, to obtain synthetic polymers using controlled methods, including radical polymerization (CRP). The use of CRP nables the synthesis of macromolecules with different compositions and complex architectures, whereas control over their structures is maintained. Moreover, the influence of sugar moieties on the roperties of...
