中文摘要 | three polypropylene/poly(ethylene-co-propylene) (pp/epr) in-reactor alloys produced by a two-stage slurry/gas polymerization had different ethylene contents and mechanical properties, which were achieved by controlling the copolymerization time. the three alloys were fractionated into five fractions via temperature rising dissolution fractionation (trdf), respectively. the chain structures of the whole samples and their fractions were analyzed using high-temperature gel permeation chromatography (gpc), fourier transform infrared (ft-ir), c-13 nuclear magnetic resonance (c-13 nmr), and differential scanning calorimetry (dsc) techniques. these three in-reactor alloys mainly contained four portions: ethylenepropylene random copolymer (epr), ethylene-propylene (ep) segmented and block copolymers, and propylene homopolymer. the increased copolymerization time caused the increased ethylene content of the sample. the weight percent of epr, ep segmented and block copolymer also became higher. |
