1.A new kind ofpolyurethane-acrylatemacromonomer was synthesized by IPDI,HEMA,PEG and EG,then it was copolymerized with methyl methacrylate(MMA),forming a novel amphiphilic polymer which contained hydrophobic and hydrophilic chains.利用异佛尔酮-二异氰酸酯(IPDI)、聚乙二醇(PEG)、甲基丙烯酸-β-羟乙...
PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells. View all Preparation The polymerization of methyl methacrylate: is readily accomplished by bulk, solution, suspension and emulsion techniques. Of these methods, bulk and suspension polymerization are mainly used for the production of...
The matrix resin was prepared with blending ofpolyurethane methylacrylateand epoxy methacrylic resin. 通过聚氨酯甲基丙烯酸酯与环氧甲基丙烯酸酯共混得到基体树脂,再添加可见光引发剂、交联单体等制成可见光固化胶粘剂,再向胶粘剂中加入无机填料制成可见光固化复合树脂。
PURPOSE: To obtain a polyurethane (meth)acrylate, excellent in water resistance and useful for coatings, adhesives, etc., by bringing a special liq. hydrocarbon diol successively into contact with a polyisocyanate and a hydroxyalkyl (meth) acrylate. ;CONSTITUTION: A hydrocarbon diol which has two...
These PUs were quite efficient hydrophobes for polyurethane (PU)-acrylate hybrid miniemulsion polymerization. It was also demonstrated from the results of differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) that the microphase separation of soft and hard phase of PUs in ...
