Abstract

The different pre-polymerization temperatures and various formaldehyde/phenol (F:P) ratios have a critical importance in the synthesis of resol phenolic resin. Understanding the reaction parameters in polymerization reactions is a prerequisite for the production of phenolic resinbased composite materials. X-Ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC) and microhardness analysis were performed to observe the effect of different pre-polymerization temperatures and various F: P ratios. The results of XRD and FTIR analysis provided an understanding of the structural conformation of synthesized resins. It was also found by the DSC and microhardness analysis that the tendency of crystallization increased for the synthesized resin (PFR250) when the prepolymerization temperature was 50 °C and the F:P ratio was 1,3, especially in parallel with increasing ether bridges.

Özet

Farklı ön polimerizasyon sıcaklıkları ve çeşitli formaldehit / fenol (F: P) oranları, resol fenolikreçinenin sentezinde kritik bir öneme sahiptir. Polimerizasyon reaksiyonlarında reaksiyonparametrelerinin anlaşılması, fenolik reçine bazlı kompozit malzemelerin üretimi için ön şarttır.Farklı ön polimerizasyon sıcaklıkları ve çeşitli F:P oranlarının etkisini gözlemlemek için, X-Işınıdifraksiyonu (XRD), Fourier dönüşümlü infrared spektroskopisi (FTIR), Diferansiyel taramalıkalorimetri (DSC) ve mikro sertlik analizleri yapılmıştır. XRD ve FTIR analizlerinin sonuçları,sentezlenmiş reçinelerin yapısal konformasyonunun anlaşılmasını sağlamıştır. DSC ve mikro sertlikanaliz sonuçlarıyla, ön-polimerizasyon sıcaklığı 50 °C ve F:P oranı 1,3 iken sentezlenen reçinenin(PFR250) artan eter köprülerine paralel olarak kristalleşme eğiliminin arttığı tespit edilmiştir.
