| 英文摘要 | The crystallization morphologies and mechanical behaviors of ipp/spp blends and the corresponding fibers were investigated in the present work. for all the investigated ipp/spp blends, the starting crystallization temperature of spp during cooling process was significantly increased with increasing ipp content. the ipp/spp blends are strongly immiscible at the conventional melt processing temperatures, in consistence with the literature results. as isothermally crystallized at 130 degrees c, spp still keeps melt state, while ipp component is able to crystallize and the spherulites become imperfect accompanied by decreasing of the crystallite size as spp content increases. the addition of spp decreases the crystallinity of ipp/spp blends and fibers. the storage modulus, et, of the ipp/spp blends is higher than that of spp homopolymer in the temperature range from -90 to 100 degrees c. the ipp/spp fibers can be prepared favorably by melt-spinning. as spp content exceeds 70%, the elastic recovery of the ipp/spp fibers is approximately equal to that of spp holnopolylner fiber. the drawability of the asspun fiber of ipp/spp (50/50) is better than that of spp fiber, which improves the fiber processing performance and enhances the mechanical properties of the final product. the drawn fiber of spp presents good elastic behavior within the range of 50% deformation, whereas the elastic property of the ipp/spp (50/50) fiber slightly decreases, but still much better than that of ipp fiber.
