Tensile yield behavior of the blends of polypropylene (PP) and styrene-ethylene butylene-styrene block copolymer (SEBS) is studied in blend composition range 0-25 wt % SEBS. Three sets of samples, (i) solution-blended compression-molded (SBCM), (ii) melt-blended compression-molded (MBCM), ...
摘㊀要:以低相对分子质量苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)和聚丙烯(PP)为原料,制得 SEBS /PP 共混料,然后通过熔融纺丝制备非织造布用SEBS /PP 弹性纤维,研究了PP 含量及纺丝条件对SEBS /PP 共混料热力学行为㊁力学性能㊁流变性能及可纺性的影响㊂结果表明:SEBS /PP 共混料与PP 的熔程均在150...
Crystallizability of the blends was decreased as the increase in SEBS content，for which the haze values of injection-molded plaques decreased. The PP/SEBS blends showed a decreased tensile strength and and a increased impact strength as compared with PP. Results of rheological study showed that ...
共混:将改性后的GNPs与PP、SEBS以不同共混顺序按表1的配比加入转矩流变仪初步混合,得到PP/GNPs(以下简称PG)、SEBS/GNPs(以下简称SG)预混物;再将预混物与干燥后的PP、PA6、SEBS和聚丙烯蜡微粉润滑剂(1 %)按表2的配比初步混合,加入...
In this paper, the generation mechanism of oxidation products during the oxidation of the polystyrene- block -poly(ethylene- co -1-butene)- block -polystyrene copolymer (SEBS)/poly(propylene) (PP) blend in air atmosphere is investigated using temperature-dependent FTIR combined with 2D correlation...
With the increase of the content of SEBS for ternary blends,the balance torque of blends increases,the hardness (Shore A) decreases,the transparency dete-riorates,the elongation at break increases. When the ratio of PP/propylene-based elastomer/SEBS is 47.5∶47.5∶5,the blend is characterized ...

Blends of recycled polypropylene (PP) with styrene-ethylene-butylene-styrene (SEBS) or styrene-butadienestyrene (SBS) can be designed specifically for the purpose of reestablishing the impact resistance of recycled PP. Recycled polypropylene (RPP) and elastomers were pre-blended in an intensive mixer...
