Synthesis and characterization of dental materials based on polymers

In this study, polymers were synthesized for using in dental applications. For this goal, HEMA, EGDM, TEGDMA, EDMA were used as difference monomers based on acrylics and crossing agent. Monomer solution were prepared by varying monomer, solvent and initiator concentration and then gelation time were determined. New samples were reprepared in the same concentration, and were taken from polimerization medium before gelation time. Then were placed in excess methanol. Lineer polymer chains in the polimerization medium were precipitated before the formation of crosslinking structure in methanol so that linear polymer structure than can be dissolve own monomers are synthesized as a powder by the evaporate methanol. First polymers, that were synthesized at 3 difference structures as HEMATEGDMA, HEMA- EGDM, EDMA- EGDM were transformed paste with UV initiator and accelerator in UV then cured and determined cure times. Key Words : Acrylates, dental materials, dental filling materials, gelation time, curing time
