Mini-emulsion preparation, kinetics of reaction and physical properties of acrylic terpolymer lattices
In this study, stable lattices of terpolymer butyl acrylate, methyl methacrylate, and styrene were synthesized by a mini-emulsion polymerization technique using tert-butyl hydroperoxide TBHP/Fe2 /ethylenediaminetetraacetic acid/sodium formaldehyde sulfoxylate redox initiators at room temperature, and the kinetics of the reaction were studied. The reaction rate was obtained from periodic samplin...
متن کاملDarnault Mirror: an Acrylic Emulsion Compensation System
This paper will discuss the evolution of the treatment for a 1751 French boiserie mirror retaining approximately 30% of its original gilding. In the first phase of the treatment, the mirror had been thoroughly analyzed and documented, tests were undertaken and cleaning and compensation method testing had commenced. This philosophical discussion was presented in a paper in the general session la...
متن کاملAcoustic Performance of Resilient Materials Using Acrylic Polymer Emulsion Resin
There have been frequent cases of civil complaints and disputes in relation to floor impact noises over the years. To solve these issues, a substantial amount of sound resilient material is installed between the concrete slab and the foamed concrete during construction. A new place-type resilient material is made from cement, silica powder, sodium sulfate, expanded-polystyrene, anhydrite, fly a...
متن کاملThermal Field-Flow Fractionation of Acrylic Copolymers
A new thermal field-flow fractionation (ThFFF) method has been developed for the separation and analysis of polyacrylates and acrylic-styrene copolymers. This important class of polymers is commonly used as pressure sensitive adhesives, in coatings and paintings, and as the basis for polyelectrolyte materials. The structure and chemical composition of these polymers play a vital role in the end...
متن کاملMechanical properties of a hydrophilic acrylic polymer.
Acrylic polymers with hydrophilic groups (i.e., ethyl hydroxyl) may be prepared that convert to a soft elastic gel by absorbing water. Such a polymer has been applied t o dentistry for use as an elastic lining material for dentures. A commercial product, Hydron, was used in this study. The linear expansion of this material after 520 hr of water immersion was found to be 20.4%. Hardness was foun...
