the interaction of the external donor (propyltrimethoxysilane - ptms) with titanium-magnesium catalysts (tmcs) containing dibutylphthalate (dbp) as internal donor, which were prepared in different ways, was studied by chemical analysis and infrared diffuse reflectance spectroscopy (drifts). the chemical composition of the catalysts after their interaction with heptane solutions of ptms, ptms/al...

Optical heterodyne-detected optical Kerr effect (OHD-OKE) experiments are presented for the supercooled liquid acetylsalicylic acid (aspirin - ASP). The ASP data and previously published OHD-OKE data on supercooled dibutylphthalate (DBP) display highly damped oscillations with a periods of approximately 2 ps as the temperature is reduced to and below the mode coupling theory (MCT) temperature T...

Introduction Tissue conditioners are used for conditioning of denture-bearing inflamed mucosa by ill-fitting dentures prior to fabricating new dentures, for relining the existing dentures, and for provisional relining of immediate dentures and ill-fitting dentures [1-2]. Tissue conditioners have also been used as functional impression materials [1-3]. Their efficacy as functional impression mat...

In this work, 1.4 mm dibutylphthalate (DBP) filled urea–formaldehyde (UF) microcapsules were used as Pickering stabilizers to create larger 140 mm microcapsules containing a second liquid phase, dicyclopentadiene (DCPD). The binary microcapsules were made by encapsulating the dispersed DCPD liquid (stabilized with the UF(DBP) microcapsules in water) via an isocyanate–alcohol interfacial polymer...
