Abstract
This paper presents a study of the reactivity for some acrylates and methacrylates with two double bonds: diethylene glycol diacrylate (DEGDA), tetraethylene glycol diacrylate (TTEGDA), dipropylene glycol diacrylate (DPGDA), tripropylene glycol diacrylate (TPGDA), ethylene glycol dimethacrylate (EGDMA), triethylene glycol dimethacrylate (TEGDMA). The reactivity was studied by photopolymerization (Du Pont de Nemours 930 DPC) and thermal polymerisation (DSC 204 Netzsch). The used initiators are Lucirin TPO and Irgacure 1700 (3%w for photopolymerization) and benzoyl peroxide (POB 1 and 3% w for thermal polymerization). Correlations between monomers structure and theirs reactivity were established. Keywords: activation energy, diethylene glycol diacrylate, tetraethylene glycol diacrylate, dipropylene glycol diacrylate, tripropylene glycol diacrylate, ethylene glycol dimethacrylate, triethylene glycol dimethacrylate, DSC, DPC
