ABSTRACT Acrylic resin/micro‐SiO 2 /polymethyl urea (AC/SiO /PMU) composites were prepared by physical blends of acrylic resin latex (AC), polymethyl (PMU), and modified SiO . The effects PMU content in the hybrid morphology properties investigated detail using transmission electron microscopy (TEM), UV‐Vis spectrometry (UV‐Vis), scanning microscope (SEM), thermogravimetric analysis (TGA), contact angle measurement. results showed that introduction into AC could increase viscosity which...
ABSTRACT Fluidity and slump loss are main technical indicators for the quality of concrete. They related to dispersion cement hydration process, greatly affected by structure superplasticizers (SPs). For purpose obtaining SPs with excellent fluidity retention, water‐soluble cross‐linked polycarboxylate ether copolymers (CLPCs) acrylic acid alkenyl alcohol type polyoxyethylene were synthesized. In order gain full understanding effect on properties in cementitious system, new paste compared...
Block copolymers (BCPs) have stimulated widespread research interest due to their applications as facile templates in the fabrication of optimized thermosets with micro– or nanostructured morphologies. In present work, a novel block copolymer was obtained from commercial poly(styrene-block-butadiene-block-styrene) (SBS) triblock precursor by two-step process including reaction hydrogen peroxide water/dichloroethane biphasic system achieve an epoxidized derivative 46 mol% degree epoxidation...
ABSTRACT Aqueous acrylic–polyurethane hybrid emulsions (PUA) were fabricated by semibatch emulsion copolymerization using a mixture of acrylic (AC) monomers in the presence an isocyanate terminated polyurethane (PU). The effects PU content on morphology and film properties here investigated detail FT‐IR, UV, TEM, SEM. TEM images clearly showed that exhibited core‐shell structure before neutralization. However, after neutralization with N , ‐dimethylethanolamine, typical particles phase...
Alkyl glycidyl ether and 3-chloropropionic acid were grafted onto alkaline lignin (KL) to obtain lignin-based alcohol carboxylate surfactant (KLS) its structure, surface tension, emulsifying ability detergency of cotton fiber investigated. Then, the was pretreated by using ultrasound activate KL molecular. The showed lower Mn narrow molecular weight distribution. absorbance ratio A1125/A1600 A1047/A1600 increased as time increased, indicating that new phenolic hydroxyl groups formed. Further...
Sodium lignosulfonate (LS) was modified by polypropylene glycol diglycidyl ether (PPGDE) for the preparation of a surfactant (GLS), and firstly used detergent builder. The effects PPGDE content on reaction properties GLS were investigated. structure studied Fourier transform infrared spectra (FTIR), ultraviolet spectrophotometer (UV), gel permeation chromatography (GPC). surface tension, critical micelle concentration (CMC), emulsifying ability, lime soap dispersing power (LSDP), detergency...
Abstract Procuring silicone rubber composite with different content of vinyl MQ resin was prepared and its thermal stability evaluated. A total 50wt% containing 5wt% exhibited optimal consequently chosen. This blended TPU at high temperature using an internal mixer to produce a modified TPU. The by firstly investigated Fourier Transform Infrared Spectroscopy (FTIR) Thermogravimetric Analysis (TGA). FTIR results indicated that negligible chemical reactions occurred between during the mixing...
The influence of 3-hydroxyhexanoate (HHx) comonomer molar fraction on the morphology and lamellar packing poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHx) thin film under spatial confinement were carefully investigated by scanning probe microscope (SPM) synchrotron radiation grazing-incidence wide-angle X-ray scattering (GIWAXS) measurements. It was found that HHx content plays an important role crystalline structure PHBHx Si substrate. evolution with increasing evident. lamellae are...
