Functionalization addresses a property gap of polyolefins and opens new perspectives due to improved surface properties in applications like composites (e.g., glass fiber reinforced polypropylene) and anti-corrosive coatings for metals. Various techniques have been developed to characterize func...

To achieve uniform dispersion of graphene in polypropylene, polypropylene-graft-maleic anhydride (PP-g-MA) as compatibilizer was compounded with graphene to obtain masterbatch, and then melt blended with polypropylene using a micro-compounder. Raman study showed the strong interfacial interactio...

To achieve reinforcement of mechanical and thermal performances of polypropylene (PP) product, this work aimed at fabrication of surface modified kaolin (M-kaolin) filled polypropylene grafted maleic anhydride (PP-g-MAH) composites with varying contents of fillers and investigation of their mech...

PurposeZanoterone (100 to 800 mg.) versus placebo was studied in 463 patients with benign prostatic hyperplasia.

Differential scanning calorimetry (DSC) data, in conjunction with Fourier transform infrared (FTIR) spectroscopy and X-ray powder diffraction (XRPD), was used to discriminate various polymorphic forms of zanoterone. The solid-state degradation rate of form IV (hemihydrate A) was found to be grea...

The aldol reactions of trimethoxysilyl enol ethers catalyzed by lithium binaphtholate were found to be powerful tools for the construction of quaternary asymmetric carbon centers. The stereoselectivities were greatly affected by the presence of water. Trimethoxysilyl enol ether derived from a cy...

An efficient method for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and thiones through one-pot three-component reaction of ethyl acetoacetate, aryl aldehyde and urea or thiourea in ethanol using 3-[(3-(trimethoxysilyl)propyl)thio]propane-1-oxy-sulfonic acid as catalyst is described. The us...

New PCL-HBPG/SiHBPG triblock copolymers composed of a polycaprolactone (PCL) core with two outer blocks of trimethoxysilyl end-capped hyperbranched polyglycidol (HBPG/SiHBPG), of varying molecular weight, have been successfully synthesised and characterised. The effect of copolymer composition a...

The solubilities of 2-(trimethylsilyloxy)ethyl methacrylate and 3-(trimethoxysilyl)propyl methacrylate in supercritical CO2 fluid were measured at many different temperature (i.e., 313.2, 333.2, 353.2, 373.2 and 393.2 K) and up to 22.49 MPa pressures using variable-volume high pressure view cell...

A homogeneous distribution of inorganic fillers and their integration with polymer matrix is the primary challenge for advancement of mixed matrix membranes (MMMs) in pervaporation. Due to well-defined structure and multi-functional groups attached to the apex silicon atoms, polyhedral oligomeri...

Biodegradable organic-inorganic composites composed of polylactide (PLA) and hydroxyapatite (HA) are important bone repairing materials, while the dispersibility of nanoscaled HA in PLA and the interfacial adhesion between HA and PLA remained unsatisfactory. In this study, poly(D-lactide) (PDLA)...

In this study, the stereocomplexation of poly-l-lactide (PLLA) and poly-d-lactide (PDLA) was monitored in real time using fluorescence spectroscopy. To introduce fluorescence probes at the beginning (i.e., α position) of the PLLA and PDLA chains, a pyrene derivative was employed as an initiator...

Poly (l-lactide-co-D, l-lactide) (PLDLLA) is a biodegradable polymer predominantly used in biomedical applications. Despite unprecedented characteristics of PLDLLA, its wettability, mechanical properties, degradation, and cell attachment are main issues to improve. In this work, different blend ...

Nonwoven polymeric materials for urological applications have been prepared from different kinds of polymers: poly(glycolide-ɛ-caprolactone) (PGCL) and poly(d,l-lactide-co-glycolide) (PLGA) with the use of electrospinning technique.
