The effect of the compatibilizer content on the curing characteristics, crosslink density, mechanical properties, heat aging properties, oil resistance, and low temperature properties were investigated. The effect of fumed silica content on the mechanical properties of FKM/MVQ blends in the presence of MVQ-g-TFEMA was also studied. The dynamic mechanical analysis indicates that MVQ-g-TFEMA acts as a compatibilizer in the FKM/MVQ blends. The mechanical properties and oil resistance of FKM/MVQ blends increase with the increasing of MVQ-g-TFEMA content up to 6 phr and the heat aging properties increase with the addition of the compatibilizer. Rubber–filler interactions in the blends increase with the increasing of the compatibilizer content. Rubber–filler interaction studies show that the presence of MVQ-g-TFEMA enhances the interfacial interaction of fumed silica and rubber matrix. The tear strength and hardness increase by the incorporation of fumed silica, and the tensile strength and elongation at break increase with the addition of the fumed silica up to 30 phr in the presence of 6 phr MVQ-g-TFEMA.","PeriodicalId":15644,"journal":{"name":"Journal of Elastomers and Plastics","volume":"463 1","pages":"539 - 560"},"PeriodicalIF":1.7,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72960649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EPDM-r was incorporated as obtained by the manufacturer (vulcanized) and also after being submitted to a devulcanization process using microwaves. The mixtures were obtained with the use of bis(α, α-dimethylbenzyl) peroxide. The elastomeric residue was characterized by gel content and scanning electron microscopy, before and after the devulcanization process. The mixtures obtained were characterized by thermogravimetric analysis, differential scanning calorimetry, and mechanical tests for resistance to traction and impact. The results of the analysis of the residues showed that the devulcanization process reduced significantly the gel content of the elastomer. The mixtures obtained demonstrated that the incorporation of vulcanized EPDM-r reduced the crystallization and fusion enthalpies, while conserving the crystallization and fusion characteristics of the thermoplastic. The mixtures showed a reduction in the deformation and traction strength; however, the incorporation of devulcanized EPDM-r led to a significant increase in the elasticity modulus values and the resistance to impact in relation to the pure LDPE.","PeriodicalId":15644,"journal":{"name":"Journal of Elastomers and Plastics","volume":"4 1","pages":"417 - 431"},"PeriodicalIF":1.7,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88926286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EVA was selectively cross-linked within the HDPE phase by transesterification reaction between ester groups of the EVA and alkoxysilane groups of tetrapropoxysilane, catalyzed by dibutyl tin oxide. Torque level and temperature in the torque rheometer chamber were monitored to follow the evolution of the EVA cross-linking during dynamic vulcanization. The degree of cross-linking of EVA in the HDPE/EVA materials was estimated by the gel content (insoluble EVA fraction). The changes in the HDPE/EVA phase morphology caused by different degrees of EVA cross-linking were investigated by scanning electron microscopy. Melt-state linear viscoelastic properties of the materials were investigated by small amplitude oscillatory shear rheometry. For the composition and processing conditions adopted in this study, the HDPE/EVA showed a coarse co-continuous phase morphology, with large EVA domains interconnected with HDPE domains. Following the dynamic vulcanization, this changed to a more refined co-continuous morphology. The linear viscoelastic relaxation behavior of dynamically vulcanized HDPE/EVA materials suggests the existence of a percolated network structure of high viscous and elastic EVA domains interconnected with thermoplastic HDPE domains.","PeriodicalId":15644,"journal":{"name":"Journal of Elastomers and Plastics","volume":"56 1","pages":"561 - 575"},"PeriodicalIF":1.7,"publicationDate":"2010-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90908786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
