Study of the Properties of Cured Epozy Resins Synthesized from Glycolyzed Wastes of Poly(Ethylene Terephthalate)
1.Introduction Poly(ethylene terephthalate) is one of the most widely used polymer for plastic packaging. This generates o lot of wastes. PET wastes coming mainly from bottles and the production of fibres can be degradated using different mechanical 1 and chemical methods (e.g., hydrolysis or alcoholysis, glycolysis, aminolysis, aminoglycolysis) 2. Products of the PET chemical recycling are used mainly for the production of unsaturated polyesters 4, polyurethane elastomers and foams5. Application of glycolysed or aminoglycolysed PET as curing agents 6, modifiers for Bisphenol A-based epoxy resins 7 and new raw materials for the synthesis of the epoxy resins 8 was also reported recently. Method of synthesis of the epoxy resins using chemically degradated glycolysed PET wastes as polyhydroxylic reagents and epichlorohydrin was proposed 9-11. Application of the new epoxy resins as reactive modifiers for low-molecular-weight Bisphenol A-based resins was studied and the relationship between mechanical properties of the resins and their structure is discussed in this work.
