Experimental misc.bility studies were performed on different c.mpositions of iPP/sPP blends, where sPP has a low syndiotac.ic.ty （[rrrr] = 81%）. c.mbining optic.l mic.osc.py, rheology, and solid state NMR spec.rosc.py, the misc.bility of the blends was investigated at different sc.les in the traditionally thought to be ＂immisc.ble＂ iPP/sPP blends. For the c.mposition of iPP/sPP （90/10） blend, it shows to be misc.ble in the melt, and furthermore, the existenc. of intermolec.lar c.ain interac.ions between sPP and iPP c.mponents was detec.ed in the solid state.

不同含量的聚砜(PSF)对环氧树脂(EP)/PSF共混物相结构有重要影响,通过对反应分相后的样品进行断面观察,发现一定PSF含量时,体系形成了层状结构.这种层状结构通常为3层,包括上下2个外层、由聚砜和环氧树脂的颗粒-基体结构组成,以及1个双连续结构形成的中间层.研究表明,这种层状结构由反应诱导相分离开始之初形成的双连续结构发展而来,由于反应和相分离的进一步发展热塑性树脂富集相的体积分数逐渐减小、以及组分间的动力学不对称而最终形成的.在一定PSF浓度范围内,不同温度固化样品时均得到了这种层状结构.改变固化剂类型,层状结构的形貌受到影响,当固化剂活性较高时,外层变薄中间层增厚.当组分间的相容性较好时,双连续结构甚至不能演化发展到层状结构.

Glass transition involves a many-body interac.ion and relaxation proc.ss. The splk of relaxation spec.rum and the extremely slow dynamic. bring into c.nsiderations of non-linearity and non-equilibrium. Some of our rec.nt findings in two measurable c.lloidal systems are reviewed, one with a simple attrac.ive interpartic.e potential and the other with a c.mpetitive （repulsive vs. attrac.ive） inter-partic.e interac.ion. With an approac. from interac.ion potential c.0}ges to the c.rresponding struc.ural and relaxation responses, along the path of reac.ing the final equilibrium, we illustrate some interesting physic. in glass formation proc.ss. Also, some reviews on the popular glass transition theories are made to remind readers to avoid artifac.s and misinterpretations.
