  • ZEOLITES WITH IMPROVED COMPATIBILITY
    Publication number: 20230211314
    Abstract: The invention relates to modified zeolite crystals comprising zeolite crystals and from 0.5% to 20%, by weight, endpoints included, relative to the total weight of modified zeolite crystals, of at least one polymeric compatibilizer, more particularly a functional polyolefin. The invention also relates to the use of the modified zeolite crystals according to the invention as a filler in a polymer matrix, for example for the preparation of composite materials.

  • Zeolites with hierarchical porosity
    Patent number: 10773965
    Abstract: The present invention concerns zeolites with hierarchical porosity having a molar ratio Si/Al of between 1 and 1.4, inclusive, of which the average diameter, as a number, is between 0.1 ?m and 20 ?m, having controlled and optimized crystallinity, and having mesoporosity such that the mesoporous outer surface area is between 40 m2·g?1 and 400 m2·g?1. The present invention also concerns the method for preparing said zeolites with hierarchical porosity.
