Chemistry, Physics and Technology of Surface| Summary: | The peculiarities of flowing and structure formation processes in polymer mixture melts with matrix polymer of various chemical nature have been investigated. It has been shown that for polypropylene/plasticized polyvinylalcohol (PP/PVA) mixtures PP, microfibers are the preference structure type even at components ratio 50:50. For other polymer mixture this ratio is the region of phase change. The value of interface tension for PP/PVA melts is lower in comparison with those for other polymer mixtures. The earlier found regularity that swelling values of extrudates characterize phenomenon of the specific fibre formation. Is not confirmed for PP/PVA mixtures. It has been found that methylsilica additives decrease melt viscosity and improve the mixture melt capability to longitudinal deformation. This permit to regulate of structure-formation processes in matrix polymers with various chemical nature. |
