“…a-the acrylate emulsion; b-the acrylosilance emulsion The signals in Fig.7 shows that the distribution of a and b are similar, but the average diameter of the particles in b is little larger than that in a. This result may be due to the cohesion between particles when C-1706 undergoes the hydrolysis and polycondensation in the copolymerization process, so that the molecular weight of b is increased and the average diameter became larger [15] . But the difference is slim, that means the infl uence of C-1706 on the particles size and their distribution is not obvious.…”

An acrylate emulsion was modifi ed by adding vinyltriisopropoxy silane (trade name C-1706). By adding the multiple emulsifi er which consists of an anionic emulsifi er, sodium dodecyl benzene sulfonate (SDBS) and nonionic emulsifier, octyl phenolic divinyl oxide (OP-10), the acrylosilane microemulsion was synthesized by seeded emulsion polymerization. The influential factors including the kind and the adding amount of emulsifi ers and the monomer variety of alkoxy silane and the added methods which infl uence on the properties of the microemulsion were investigated. It is found that SDBS and OP-10 as multiple emulsifi ers with mass ratio of 1:1 and the adding amount of 2.5%-3.5% can act on co-effect for emulsion polymerization. The C-1706 possesses bulky isopropoxy substituent that can reduce hydrolysis reactivity during the polymerization process, so as to not only make the process smoothly but also advance the store stability of the emulsion. Moreover, the latter-addition mode of C-1706 can restrain its hydrolysis activity and polycondensation reaction during the polymerization process of the emulsion. The structure, the fi lm cross section, the particle size and its distribution of the microemulsion were analyzed by the Fourier Transform Infrared Ray Spectrum (FT-IR), Scanning Electron Microscopy (SEM) and a particle size analyzer,respectively. The results show that the particle diameter of the modifi ed microemulsion can be controlled between 50 and 70 nm and its fi lm hardness is 7.3. Only adding 1.5% of C-1706 into the system of emulsion polymerization can apparently improve the weathering resistance of the microemulsion, which undergo degradation with chromatism( E) is 1.6 after 3 600 hours of QUV-aging.

“…The mixture was stirred at 90°C for 1 h. For the healing agent, reactive poly(bisphenol A-co-epichlorohydrin) with glycidyl end-group ( of 6100 g/mol) was capped with malonic acid (Oprea et al 2000). In this synthesis, linear polymer (20 g, 0.003 mol) was introduced to the beaker and melted in an oil bath.…”

“…The hydroxyl groups enhance polarity and facilitate adhesion and pigment wetting properties. 1 Different types of VE resins can be prepared by changing the epoxy resin and the acid used. The epoxy backbone provides toughness and flexibility to cured VE films, while the carbon-carbon and ether bonds of the resin improve the chemical resistance.…”

Mono-or di(meth)acrylate-terminated derivatives of diglycidyl hexahydrophthalate (ER) were prepared by reacting 1 : 1 or 1 : 2M ratio of ER and methacrylic acid or acrylic acid. These vinyl ester (VE) resins were characterized by determining epoxy equivalent weight, acid number, and molecular weight by gel permeation chromatography. Structural characterization was done by FTIR and 1 H NMR spectroscopy. In the 1 H NMR spectra of acrylate-terminated VE resins, three proton resonance signals were observed in the region 5.8 -6.4 ppm due to vinyl group while in methacrylate-terminated VE resins only two proton resonance signals due to vinylidene protons were observed at 5.6 -6.1 ppm. The Brookfield viscosity (room temperature (25 Ϯ 2)°C) of these resins diluted with varying amounts of MMA was determined at 20 rpm. Curing behavior was monitored by determination of gel time and differential scanning calorimetry. An exothermic transition was observed in the DSC scans in the temperature range of (81-150)°C. Isothermal curing of MMA-diluted VE resins containing AIBN as an initiator was done at 60°C for 2 h in N 2 atmosphere, and then heating for another 2 h in static air atmosphere. Thermal stability of isothermally cured resins in N 2 atmosphere was evaluated by thermogravimetric analysis. All cured resins decomposed above 310°C in single step. Thermal stability of the cured resins having acrylate end caps was marginally higher than the resins having methacrylate end groups.
