Abstract
The reaction of photopolymerisation of bis(4-methacryloylmethylphenyl)sulphide (BMcMPhS) and bis(4methacryloylmethylphenyl)sulphone (BMcMPhSu) with the typical vinyl monomers: methyl methacrylate (MMA) and styrene (St) in the presence of the two photoinitiators: Irgacure 651 and Darocur 1173 are presented. The influence of percentage concentration of BMcMPhS and BMcMPhSu on the gelation times of the prepared copolymers was studied. The effect of the used photoinitiator concentrations on gelation times was also investigated. For the chosen copolymers, mechanical properties including tensile strength, elongation at break, Young modulus, Brinell’s and Shore’s hardness were determined. The results showed that copolymers with MMA had shorter gelation times than those with St. Gelation times were shorter when Darocur 1173 was used as a photoinitiator. An increase of Darocur 1173 concentration caused a decrease of gelation times, whereas in the case of Irgacure 651 the opposite relation was observed. 26 Refs.
