“…Jia et al 23 well grafted ESO onto polyvinyl chloride (PVC) based on biomass monomer, such that the glass transition temperature of PVC can be reduced, and the mechanical properties turn out to be more flexible without migration. Yue et al 24 prepared internally toughened phenolic resin (ESO-IT-PR). The flexible ESO epoxy exerts a significant toughening effect while crosslinking with the phenolic resin to form an internally toughened network, which takes on critical significance in enhancing the solder leaching resistance of copper clad laminate prepared with this modified phenolic resin.…”

In this study, two types of epoxy soybean oil (ESO) modified vinyl chloride acrylate copolymer emulsion (vc‐m), that is, physically modified vc‐m‐1 and chemically grafted vc‐m‐2, were well prepared initially. The chemical structure, particle size distribution, surface morphology, flexibility, and mechanical properties of the three emulsions were studied through Fourier transform infrared analysis, proton nuclear magnetic resonance analysis, nano‐size analysis, atomic force microscopy, dynamic mechanical analysis, as well as tensile test. Compared with vc‐m, the glass transition temperature (Tg) of vc‐m‐1 and vc‐m‐2 was reduced by nearly 28%, the tensile strength was increased by 50%, and the elongation at break was improved by 70.5% and 70.7%, respectively. No significant difference was identified between vc‐m‐1 and vc‐m‐2. Furthermore, the chemical reaction mechanism and internal plasticizing mechanism of vc‐m‐2 synthesis were discussed. ESO enhanced the low‐temperature brittleness and mechanical strength of the emulsion, and vc‐m‐2 exhibited better migration stability while maintaining the identical flexibility and mechanical properties as vc‐m‐1. The modified emulsion is capable of adapting to low ambient temperatures when applied to coatings and road adhesives while showing promising applications.

“…The maximum storage moduli of those polymers appeared in the range 1–2 GPa. According to the Situ et al, the addition of ESO to phenolic resins increased the flexibility of the phenolics, and they found that the ESO‐phenolic resin matrix was a cheap matrix with excellent properties . There was no literature about the polymerization reaction and mechanical properties of ESO and maleate esters of the oil‐soluble phenolic resin.…”

In this study, the polymerization reactions of epoxidized soybean oil (ESO) with the maleate half‐esters of oil‐soluble resoles and the properties of the final products were demonstrated. The maleate half‐esters of the dimeric oil‐soluble resoles were obtained by the esterification reaction of maleic anhydride with a p‐tertiary butyl phenol (p‐TBP) resole and p‐nonyl phenol resole resins in the first step. The monomers were characterized by IR and 1H‐NMR techniques. Then, the oil‐soluble resole maleates were polymerized with ESO to obtain tough and load‐bearing thermoset materials. The thermal and mechanical properties of the materials were determined by dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, and tensile strength testing. The tensile strengths and storage moduli of the crosslinked polymers varied between 0.17 and 13 MPa and 10 and 1088 MPa, respectively. The elongation percentages of the materials were between 1 and 128%. The thermal resistance of the thermosets was measured as the 5% weight loss temperature. The reaction product of the ESO and maleate ester of p‐TBP showed the highest 5% weight loss at 247°C. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41457.

BLENDS OF NOVOLAC RESINS WITH EPOXIDIZED ELASTOMERSSummary -This paper presents the results of a study on selected properties of the blends of novolac resin with natural rubber (NR/NBR) and styrene-butadiene-styrene block copolymer (SBS/ESBS) with various degree of double bond epoxidation. The differences in properties indicate that the reaction between blend components took place. It was found that the degree of epoxidation, the type and content of elastomer as well as the hardening conditions, i.e. temperature, time and urotropine addition, have a significant effect on the blend properties and indirectly on the reactivity of the system.
