Abstract
Ethylene-vinyl acetate (EVA)grafted 2,4,6,8-tetravinyl-2,4,6,8-tetramethylcyclotetrasiloxane (V4) polymer EVA-g-V4 was prepared by free-radical solution grafting reaction. The results of the purified grafted products by FT-IR, 1H NMR, XRD, TG and DSC show that V4 has been successfully grafted onto the main chain of EVA. The effects of the dosage of V4 and BPO on grafting ratio were studied. When the dosage of V4 was 6.0 wt%, and the dosage of BPO was 0.8 wt%, the grafting ratio was up to 1.4%. The cross-linking behaviour was verified by SEM. Compared with pure EVA film, the peel strength, mechanical properties, volume resistivity and hydrophobicity of EVA-g-V4 film all improved with increasing grafting ratio. This work provides a new option in the field of photovolatic encapsulation materials.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
