“…[ 4 ] Bitterrich first reported the resin curing of unsaturated natural rubber (NR). [ 5 ] Wildschut studied the curing of NR using different commercially available resols and reported simultaneous resin self‐condensation and the reaction with rubbers. [ 3 ] For the first time, Tawney and Little reported the application of phenol‐formaldehyde (PF) resol resin for curing the tire bladder with superior thermal stability.…”

In the present work, biophenol and furfural‐based resol resin was synthesized and utilized for the very first time to cure styrene butadiene rubber (SBR). The reaction was studied over a range of times, temperatures, pH, and furfural to biophenol ratios to fix the optimum conditions. Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy revealed the functional groups and chemical structure of the synthesized resin, respectively. An exothermic peak for the resin curing appeared at 143°C in the differential scanning calorimetry thermogram of the resin. Then, the biophenol‐furfural resin was utilized for the curing of SBR. The synthesized resin increased the tensile strength of the raw rubber from 0.20 ± 0.01 MPa to 1.22 ± 0.10 MPa at 10 phr loading, and the crosslink density was 2.56 × 10−5 mol/mL. The activation energy for curing SBR containing 10 phr resin was 97 kJ/mol. The storage modulus of the resin‐cured compound was improved. The glass transition temperature of the raw SBR was also shifted from −43.8 to −42.3°C when 10 phr resin was used for the curing. Hence, for the first time, this work reported the utilization of biophenol‐biosourced furfural resin to cure rubbers.

immovable property and building owner pays the price. The contractor undertakes to built the construction contract with the qualities agreed upon in the contract. Otherwise, it will be the case that the debt is not build as required. There is a distinction between defective fulfilment and incomplete fulfilment in the Turkish Legal System regarding not fulfilling it as required. Because these concepts differ in terms of definitions, provisions to be applied, and the arrangements they are in. But this distinction is not that in the public construction contract one of the parties of the contract is the state representing the public power and international construction contract the party is a foreign government agency and the other party is a company that is subject to another legal system. This situation arises public procurement legislation is not legislated on a regular basis. In terms of the international construction contract, the Anglo-Saxon Law System does not have such a distinction, so the same provisions are applied to the defective and incomplete fulfilment.
