Copolymers of methyl methacrylate(MMA) with polypropylene glycol diacrylate(PPGDA) and polypropylene glycol dimethacrylate(PPGDMA) have been synthesized. The characterization of synthesized copolymers are carried out using the techniques such as elemental analysis, Fourier Transform Infrared Spectroscopy(FTIR) and Differential Scanning Calorimetry(DSC). FTIR studies showed that double bond of MMA and crosslinker has reacted. During the reaction between  MMA and PPGDA or PPGDMA double bond reacts on both ends and formed the crosslinked network structure. DSC studies showed that Glass Transition Temperature(T_g) for three copolymers are lower  while for one copolymer it is slightly higher than that of polymethylene methacrylate(PMMA). Higher value of T_g suggests that crosslinking has increased in this copolymer while lower value of T_g indicates lower crosslinking level.
