“…The hybrid polymers are very attractive because they have the potential to combine the useful properties of each component. Numerous studies have been carried out for the preparation of such polymers from methyl methacrylate (MMA) and alkyd resin based on linoleic acid [10] and from butyl acrylate and alkyd resin based on linoleic and linolenic acid [11] . It was found that the hybrid polymers have good adhesion, good drying rate and chemical resistance [11] .…”

Glycerol phase obtained from waste cooking oil-based biodiesel production, was utilized. By suitable treatment, crude glycerol (glycerol content 80,8%) and free fatty acids (98,8% content and iodine value 124,3 gI2/100 g) were obtained from it. Aiming to obtain coatings with good characteristics, modification with MMA was carried out. Composition and structure of copolymers were confirmed by 1H NMR. Assessment of the main characteristics of the prepared films from the copolymers, showed that they have improved hardness, drying ability and resistance to alkaline substances.

“…Rubber and other plastics such as polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) are used as soft anti-skid particles. Ceramic particles and natural sand are used as hard anti-skid particles [6]. In this research, the pavement surface for preventing slip was created by combination of NR and Methyl methacrylate (MMA) resin for coating on the pavement surface which may increase friction, abrasion and wear resistant.…”

The efficiency of the modify natural rubber (NR) combination with methyl methacrylate (MMA) monomer for pavement surface was studied. The modified coating for pavement surface consisted of MMA resin and natural rubber compound (NRC) at the weight ratio of 70:30, 60:40, 50:50, 40:60 and 30:70, respectively. The effect of rubber in MMA was studied in terms of hardness (shore A and pencil tests), adhesive, abrasion and shear strength. The results showed that hardness (shore A) and adhesion of the compound coating slightly decreased with addition of NRC. Abrasion, hardness pencil tests and shear strength notably reduced as decreasing MMA and increasing NRC concentration. The most optimum sample satisfing the pavement surface standard is M7N3 consisting of MMA:NRC of 70:30.

“…Direct addition of acrylic monomers onto the fatty acid double bonds was not observed. Gan et al 8,9 reported copolymerization of oleic alkyd resin with MMA in toluene in the presence of benzoyl peroxide. From 1 H NMR results, the decrease of the oleic double bond concentration was observed, and the grafting of both monomers was found to be across the double bonds.…”

Four model alkyds were prepared by the fatty acid process using a single fatty acid (stearic, oleic, linoleic, or linolenic acid) with phthalic anhydride and glycerol. These model alkyds were reacted with methyl methacrylate (MMA) in the presence of benzoyl peroxide or azobis(isobutyronitrile). 1 H NMR, 2D gradient heteronuclear multiple quantum coherence NMR, matrix assisted laser desorption ionization mass spectrometry, solvent extraction, and gas chromatography were used to evaluate each model alkyd system. The conversion of MMA was quantified, and the grafting mechanism of MMA onto each model alkyd was elucidated. In general, both polymerization rates and MMA conversions were inhibited in the presence of alkyd resins. For oleic alkyd model systems, the grafting site was primarily located at the double bond on the fatty acid chain. Both the homopolymerization and copolymerization of the MMA are significantly retarded by chain transfer of the hydrogen from the double allylic site in the linoleic and linolenic model systems. For the linoleic alkyd and linolenic alkyd model systems, the grafting reaction predominately occurred at the activated double allylic methylene group on the fatty acid chain via hydrogen abstraction by the primary radical and MMA radical, followed by grafting in a termination reaction with a propagating MMA radical.
