求化工专业的英语翻译高手，帮帮忙，软件翻译的别进，谢谢

Two styrene–butadiene–styrene block (SBS) copolymers which differ in weight average molecular weight and two base asphalts (from local crude source, Argentina) had been blended under different experimental conditions. Rotational viscosity, fluorescence microscopy, size exclusion chromatography (SEC) and FT-IR spectrometry were used in order to study the rheological and morphological changes of the blends during their manufacturing. Our results show that the high shear rate and temperature used during this procedure induce the SBS copolymer degradation and the degradation fragments distribution into maltenic asphalt phase. These events are responsible for the observed changes. The optimal time which produces the best rheological properties of modified asphalt depends on the blend composition and on the shear rate used.
如果翻译的很专业 可加分 谢谢

两个平均分子量不同的苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）和两个基质沥青（采用来自阿根廷当地的原材料）在不同的实验条件下混合。为了研究其在生产过程中的发生的流变学和形态学的变化，我们采用旋转粘度法，荧光显微镜法，排阻色谱法（SEC），红外光谱法等方法。我们的结果表明，高剪切率和温度的控制能够催化SBS降解并且这些降解碎片分布于……（这句我也搞不懂）。这就是观察到的变化的原因。在生产改良沥青中，最佳的流变性能的最佳时间取决于混合物的组成和剪切率使用。
