NEW MATERIAL:2-(Tricyclo[5,2,1,0<2.6>]-3,4-dibromodecylthio) ethylmethacrylate expressed by formula I. USE:A raw material of optical plastic. The resin containing the compound expressed by formula I as a main component has high refractive index and excellent transparency and suitable as an optical plastic. PREPARATION:Dicyclopentadiene and 2-mercaptoethanol are brominated according to the reaction formula and the resultant product is reacted with a methacrylic acid derivative (X is H or alkali) to provide the compound expressed by formula I. When the compound expressed by formula I is polymerized by itself or copolymerized with a compound having various kinds of olefinic double bonds, a polymer containing Br and S in side chain or oligomer is obtain. These polymer, etc., are used also as an agent for improving adhesion with a metal or glass and flame retardant of resin.
