摘要: In this work, molecular structures, dynamic mechanical properties and glass transition temperatures of microbe coagulated natural rubber (NR) samples were analyzed by using pyrolysis gas chromatography-mass spectrometry (py-GC/MS), rubber process analyzer (RPA) and dynamic mechanical thermal analysis (DMA). And the cross-linked network structures and mechanical properties of the corresponding NR vulcanizates were further determined by using nuclear magnetic resonance (NMR) crosslink density spectrometer (XLDS-15) and universal testing machines. The results show that NR raw rubber produced by rapidly coagulated with microorganism exhibits a simple molecular structure composition and good dynamic mechanical properties, and the corresponding NR vulcanizates possess the aggregation structure of high cross-linked density, a high glass transition temperature of -61.5. and high mechanical properties (tensile strength reaches 25.2 MPa), as compared with that coagulated with acetic acid.
