Cn. Cascaval et al., CURING OF SOME EPOXY-ACRYLATE GLYCIDYL ETHERS BASED ON PARA-ALKYL SUBSTITUTED PHENOLS, Polymer degradation and stability, 55(3), 1997, pp. 281-285
Curing of epoxy-acrylate glycidyl ethers based on phenol and para-alky
l [-CH3, -C(CH3)(3), -C9H19] substituted phenols in the presence of be
nzoyl peroxide was examined by differential scanning calorimetry at di
fferent heating rates. The tested monomers polymerize first as acrylic
monomers and the reaction continues by the curing process only in the
case of the epoxy-acrylate glycidyl ethers of para-alkyl substituted
phenols, when insoluble polymers were obtained. The kinetic parameters
of the curing reaction were determined using different calculation me
thods (Barrett, Freeman-Carrol, Kissinger). The activation energy vari
es in the range 64-86 kJ/mol and the order of the curing reaction is s
imilar or equal to 1 with slight variations. (C) 1997 Elsevier Science
