Crystallization mechanism of polypropylene random copolymer / maleic anhydride functionalized homopolypropylene / aluminum hydroxide based nanocomposites
Анотація
Filler particles can increase or decrease the rate of crystallization of a semicrystalline polymer, affect the growth of crystals of polymer matrices, and the effect of nucleation in the melt. From a practical point of view, the study of the kinetic regularities of the crystallization process of polymer composite materials is important when selecting the cooling mode for composites. A number of works have proven the applicability of Avrami's theory to the study of the crystallization process in polymeric materials in the region of the first-order phase transition [1–3]. The presented work provides information on the crystallization mechanism of polymer composite materials based on polypropylene random copolymer / maleic anhydride functionalized homopolypropylene / aluminum hydroxide (PP-R/PPH-g-MAH/Al(OH)3), which was studied using the dilatometric method.
