A novel polymerizable monomer represented by the formula (I) useful as a raw material for the high surface hardness transparent resin. ##STR1## wherein R is an aliphatic residue having or not having an oxygen atom, an alicyclic ring, a heterocyclic ring or an aromatic ring, or an alicyclic residue, l is 0 or 1, each of i and j is an integer of 1 or more, and when l=0, i=j=1, when l=1, (i+j) is 4 or less, when j=1, X is oxygen or sulfur, when j.gtoreq.2, all X's are oxygen or sulfur, or one X is oxygen and the other X's are sulfur, or one X is sulfur and the other X's are oxygen. The high surface hardness transparent resin comprises a crosslinked polymer prepared by copolymerizing a monomer (A) represented by the formula (I) as above and a monomer (B) containing one or more functional groups of at least one kind selected from the group consisting of CH.sub.2 .dbd.CH--C(O)--O--, CH.sub.2 .dbd.C(CH.sub.3)--C(O)--O-- and ##STR2##
一种由式(I)表示的新型可聚合单体,可作为高表面硬度透明树脂的原料。其中,R是具有或不具有氧原子、脂肪族残基、脂环烷基、杂环烷基或芳香环的脂肪族残基,l为0或1,i和j各自为1或更多的整数,当l=0时,i=j=1,当l=1时,(i+j)为4或更少,当j=1时,X为氧或硫,当j≥2时,所有的X均为氧或硫,或者一个X为氧,其他的X为硫,或者一个X为硫,其他的X为氧。高表面硬度透明树脂包括通过共聚合上述式(I)表示的单体(A)和含有至少一种选自CH.sub.2.dbd.CH--C(O)--O--、CH.sub.2.dbd.C(CH.sub.3)--C(O)--O--和的功能基团的单体(B)的交联聚合物制备而成。
