“…AIBN was the initiator employed. NMR spectra showed the presence of acrylic blocks the pendant fatty acids and the formation of homopolyacrylate [24] . Hybrid waterborne alkyd-acrylic dispersions with solid content of 40 wt%, free from any surfactant and organic solvent, were synthesized by a melt co-condensation reaction between an acrylic prepolymer bearing carboxylic groups and an alkyd resin by a phase inversion process.…”

SbstractFour waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ammonium persulfate (AP) as initiators. The reaction between HBR and acrylic monomers was evidenced by differential scanning calorimetric (DSC), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The conversion percentage, glass transition temperature (T g ), content of acrylic polymer (determined by soxhlet extraction) and molecular weight increased with the content of acrylic monomers used in the synthesis. The main structure formed during the synthesis was the HBRAA. The analysis by dynamic light scattering (DLS) showed that the particle size distribution of HBRAA2, HBRAA3 and HBRAA4 resins were mainly monomodal. The film properties (gloss, flexibility, adhesion and drying time) of the HBRAA were good.

“…It was shown that the RAFT mediated reaction imparted a more controlled free radical process for the synthesis of acrylic-alkyd materials. Use of the alkyd macro-RAFT agent provided a new path to acrylic-alkyds that imparted a more controlled way to tailor specific material properties (39).…”

“…The resulting material was then utilized as the RAFT chain transfer agent to affix acrylic blocks onto the alkyd backbone. Butyl acrylate, ethyl acrylate, methyl methacrylate, and ethyl methacrylate were the acrylic monomers used to achieve the acrylic blocks both individually and in combination (39).…”

A new method for the synthesis of autoxidatively curable acrylated alkyds is demonstrated. Acrylic block is grafted onto the backbone of the alkyd chain via atom transfer radical polymerization (ATRP) polymerization. The acrylated ATRP copolymers are compared to RAFT copolymer and both are characterized using quantitative 1H NMR, 13C NMR, and 2D‐NMR spectroscopy. In particular, the autoxidative curing of ATRP polymerized acrylated alkyd is compared to the RAFT polymerized acrylated alkyds using Fourier transform infrared spectroscopy (FTIR) spectroscopy. The analysis finds that the autoxidation of the RAFT acrylated alkyds is inhibited. It is postulated that the thiocarbonyl functionality hinders the autoxidative reactions. The performance of autoxidatively cured ATRP polymerized acrylated alkyd coatings is evaluated using tensile, viscoelastic, and general coating properties. Alkyd‐acrylic copolymer coatings show improved hardness, glass transition temperature, and drying time. General coating properties such as cross‐hatch adhesion, methyl ethyl ketone (MEK) resistance, and impact resistance are maintained except at higher acrylic concentrations.
