Grafting Polybutadiene onto Surfaces of Talcum Powder by Spray-Drying Technology and Modification of EPDM Rubber
In this contribution, we reported the investigation of EPDM rubber reinforced by talcum grafted polybutadiene (MSi-Talc). First, poly (3-methacryloxypropyltrimethoxysilane)-b-polybutadiene-b-poly(3-methacryloxypropyltrimethoxysilane) (PMSi-b-PB-b-PMSi) triblock copolymer was synthesized by esterification reaction and RAFT polymerization of 3-methacryloxypropyltrimethoxysilane. Second, talcum powder (Talc) was spraying with PMSi-b-PB-b-PMSi solution and drying to obtain modified talc (MSi-Talc). MSi-Talc and Talc were incorporated into EPDM simultaneously. It was found that Talc in the EPDM/MSi-Talc vulcanizates was much better distributed and dispersed than in the EPDM/Talc composites. Compared to Talc dispersion and Talc-rubber interaction of the EPDM/Talc composites, the mechanical properties (tensile strength, elongation at break, and tear strength) of the EPDM/MSi-Talc composites were significantly improved, and the compression set of the EPDM/MSi-Talc composites was greatly decreased and much lower than that of the EPDM/Talc composites.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
