COMPOSITIONS BASED ON MODIFIED PHENOL-FORMALDEHYDE OLIGOMERS

Abstract

The synthesis, structural characteristics, and performance properties of composite materials based on modified phenol-formaldehyde oligomers (PFO) and polyvinyl chloride (PVC) were investigated. The functionalization of the phenol-formaldehyde oligomer was carried out to enhance its reactivity and compatibility with the PVC matrix. The physicochemical, mechanical, and thermal properties of the resulting compositions were characterized using Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and mechanical testing. The research results demonstrated that the synergistic use of modified PFO with PVC significantly improves the thermal stability, mechanical strength, and chemical resistance of the composite material. The synthesized composites hold significant potential for applications in various fields, including construction, electrical and electronics, transportation, and the coatings industry
