It was reported that after the rapid formation of a gel by mixing of MMA and samarium triisopropoxide, the PMMA materials containing samarium were prepared by the in situ polymerization, the so called the non-water gel in situ polymerization. The effect of samarium triisopropoxide on the structure and properties of PMMA was studied. The results showed that by the increasing of samarium mass fraction the linear structure of PMMA containing samarium changed into crosslink network and resulted in improvement of the properties, such as resistance to heat and solvent, storage modulus. ESEM revealed the crosslink network structure of the PMMA material and no conglomerate; the samarium element was uniformly distributed. Moreover, the PMMA materials exhibited the characteristic fluorescence of samarium ion. In the concentration range studied, the fluorescent strength increased with the increasing of samarium mass fraction.
