摘要

The title compound

thiodiglycol dimethacrylate (TDGDMA)

was synthesized from thiodiglycol and methacryloyl chloride by phase transfer catalysis reaction

and its structure was confirmed by FTIR and 1H-NMR analyses. TDGDMA possesses good polymerizability to produce a homopolymer resin with excellent transparency (T%

90)

moderate refractivity (nd20

1.55)

lower dispersivity (Abbe's number

50.6) and higher glass transition temperature (Tg

119℃). Through copolymerization with styrene (St) or styrene-4

4'-bismethacryloyloxydiphenylsulfone (BPSDMA)

many properties of the copolymer such as refractive index

Abbe's number

strength

onset wavelength in the UV region and density were significantly modified. A copolymer resin with balanced properties between refractive index and dispersion was produced at the weight ratio of TDGDMA:St:BPSDMA (25:50:25)

where nd20 and Abbe's number are 1.5815 and 36.5

respectively.
