METHOD FOR THE PREPARATION OF POLYMER MIXTURES, MIXTURE PREPARED ACCORDING TO THE METHOD AND ITS USE

Method for processing a mixture of polymers which are incompatible as regards processing in shaping processes, such as, for example, by extrusion or the like, in which a first part of the mixture, which consists of a material which is substantially uniform as regards the chemical substance group, is...

Beschreibung
Zusammenfassung:	Method for processing a mixture of polymers which are incompatible as regards processing in shaping processes, such as, for example, by extrusion or the like, in which a first part of the mixture, which consists of a material which is substantially uniform as regards the chemical substance group, is separated off; a second part of the mixture is subjected to further processing which leads to surface enlargement and/or surface modification of the components; and subsequently the first separated-off part of the mixture and the second further-processed part of the mixture are combined again and processed to form a blend in which the second part of the mixture is essentially uniformly distributed in the first part of the mixture, so that processing the blend in a shaping process gives a substantially uniform product, a blend which can be produced according to said process and the use thereof.
