OBJECTIVES: The aim of this study was to synthesize a novel ampiphilic polyalkenoic acid copolymer based on acrylic acid and a methacrylic macromonomer of Triton X-100 and determine the efficacy of the novel copolymeric polyalkenoic acid in the formation of glass-ionomer cements. METHODS: Two water soluble copolymers of acrylic acid (AA) and a new amphiphilic macromonomer derived from Triton X-100 (MT) were prepared via radical copolymerisation at 60 degrees C, using azobisisobutyronitrile (AIBN) as the initiator and used to formulate conventional glass-ionomer cements with reactive glass fillers. The acid-base reaction was carried out by reacting aqueous solutions of the new copolymer (40 and 50%) with a commercial aluminofluorosilicate glass as used in conventional glass-ionomer cements. The efficacy of the new copolymer in the formation of glass-ionomer cements was investigated and preliminary results on setting parameters, FTIR analysis, mechanical properties and SEM analysis are reported in this paper. RESULTS: The copolymers were synthesized and characterized and further used to successfully prepare glass-ionomer cements. The experimental cements exhibited longer setting and working times in comparison to conventional glass-ionomer cements and the inclusion of tartaric acid enhanced the mechanical properties, which were comparable to the commercial glass-ionomer cement, Fuji IX. SIGNIFICANCE: Glass-ionomer cements prepared using ampiphilic comonomers is expected to influence their behavior in both polar and non-polar environments. As bulky side chains have been incorporated within the polymeric chain it is expected to affect the reaction kinetics of the acid-base reaction. |
