DEVELOPMENT OF A NEW GRANULATION TECHNIQUE I.

The described drop technique allows to prepare spherical granules possessing high mechanical strength. The properties of the granules can be influenced - besides by the technological conditions - by varying their composition. The release rate of the active agent incorporated in the product can. e.g., be changed by varying the ratio and kind of the support and the polymer, resp

MODIFICATION OF THE PROPERTIES OF POLYOLEFINS WITH LOW AND HIGH MOLECULAR MASS ADDITIVES

For about 10 years intense research work has been going on for the modification of the properties of polyolefins. The effect of surfactants, elastomers and filling materials has primarily been investigated upon semicrystalline polyolefins. Studies on interfacial interactions as well as on deformation mechanisms enabled the prediction of the properties of polymers. By determining the rules of modification, the interfacial interactions and the structure of the interfacial layer new polymer compositions called MODYLEN product family with favourable properties have been developed

DATA TO THE ANALYSIS AND PREPARATION OF NON-IONIC TENSIDES

Hydroxyethylation has been stated to be equally well catalyzed by alkali hydroxides, amines and acids. In the case of different types of catalysts the effect of reaction parameters was investigated and the distribution of oligomer homologues determined. The Weibull-Törnquist effect was experimentally confirmed and its theoretical explanation given

PROTEIN AND AMINO ACID CHEMICAL STUDIES

A cross-linking procedure not deteriorating the physico-chemical characteristics of wool has been elaborated. The thermal destruction processes in wool have been clarified. Solutions have been found for accelerating and inhibiting reactions taking place between wool and formaldehyde. The reactions between L-Iysine and formaldehyde as well as L-arginine and formaldehyde have been identified. Procedures have been elaborated for the practical utilization of the reaction products
