New Type

The ethyl glycol vinyl ether polyoxyethylene ether (EPEG) is a new type of macromonomer to synthesize polycarboxylate superplasticizer (PCE), which has higher reactivity due to the unsaturated double bond and easily to polymerization. The EPEG slump retaining typed PCE can be synthesized by free radical polymerization though EPEG, acrylic acid and hydroxyethyl acrylate (HEA). The HEA had the greatest influence on slump retaining performance. High polymerization conversion rate of EPEG typed PCE was beneficial to improve the concrete performance.

A new method for synthesizing magnetically responsive Fe3O4@UA@AA nanoparticles have been reported in this paper. The superparamagnetic Fe3O4@UA nanoparticles were prepared via carboxyl-functionalization of 10-undecenoic acid and Fe3O4@UA@AA made by a polymerization of 10-undecenoic acid on the surface of nanoparticles with acrylic acid. Thus the magnetic nanoparticles were functionalized with carboxylic groups. The compositions of as-prepared nanoparticles were characterized by FTIR, TGA, TEM, VSM and conductivity titration. Under optimized experimental conditions, Fe3O4@UA@AA nanoparticles with diameter of about 20 nm and 0.437mmol/g of carboxyl groups and 65 emu/g of saturation magnetization were prepared successfully.
