Result of investigations has been shown that these additives improve fiber-formation of polypropylene microfibers in copolyamide matrix polymer. The diameter of microfibers in compatibilized mixtures is much smaller that in binary mixtures. Stabilizing action of the additives was confirmed by the data on an increase of the lifetime of PP liquid streams in CPA matrix, and significant decrease in the interfacial tension. The additive content increases the melt viscosity of PP/CPA/PHMGH composition due to specific interactions between polyhexamethylenguanidinchloride and CPA macromolecules. The viscosity of mixture melts containing polyhexamethylenguanidinephosphade is reduced as compared with the viscosity of PP/CPA mixture melt. The capability ofthe PP/CPA/additive mixture melts to be longitudinally deformed increases. Product Description popup.authors popup.nrat_date 2020-04-02 Close
