Web让知嘟嘟按需出方案. 产品. 专利检索 WebThe magnitude of adhesion of two phases may be deduced from results collected by various experimental techniques. A Flory-Huggins interaction parameter (χ₂₃') was earlier successfully used in the characterization of polymer blends. We propose to express the magnitude of modified filler/polymer interactions by using χ₂₃'.
