【摘要】 本文研究了 Phenoxy/PMMA,Phenoxy/PS 共混物的力学性能和形态,讨论了 PMMA、PS 二种脆性高聚物做为分散相时,对 Phenoxy 的增韧的作用,结果表明 PMMA 对 Phenoxy 有明显的增韧效果,PS 的存在亦只能提高 Phenoxy 的断裂伸长率。更多还原

【Abstract】 Blends of Phenoxy/PMMA and Phenoxy/PS were Prepared by XSS-300 To-rque Rhevmeter and examined with tensile test and morphological analysis.As aresult,when the briltle polymers(PMMA and PS)are dispersed into the toughmatrix(Phenoxy),the toughness of matrix is increased.Yield stress,yieldstrain,tensile modulus,and elongation value at break show significant positivedeviation and have the maxima at a range of about 10% PMMA.更多还原
