    • A synthetic resin lens made from a cross-linked polymer prepared by (co)polymerizing a monomer composition comprising the following components (A) and/or (B) as the essential ingredient and optionally containing a component (C) comprising a monomer copolymerizable therewith. The lens has a high cross-linking density, a low specific gravity, and good optical characteristics. Component (A): an ester prepared from (1) a diol (a) prepared by reducing a dimer of a C16-C18 unsaturated fatty acid and/or a diol (b) prepared by reducing a dimer of a lower alcohol ester of a C16-C18 unsaturated fatty acid and (2) acrylic or meth-acrylic acid. Component (B): an ester prepared from (1) a triol (a) prepared by reducing a trimer of a C16-C18 unsaturated fatty acid and/or triol (b) prepared by reducing a trimer of a lower alcohol ester of a C16-C18 unsaturated fatty acid and (2) acrylic or meth-acrylic acid.

    • A monomer mixture which is useful for synthesizing polymers used as the material of various optical resins and has a hydroxyl value of 0-134 KOHmg/g. It is produced by the esterification between a mixture comprising substantially dimerdiol and trimertriol in aweight ratio of from 30/70 to 99/1 and (meth)acrylic acid or transesterification between the diol/triol mixture and a lower alkyl (meth)acrylate. The diol/triol mixture is prepared by polymerizing a feed mixture having an iodine value of 30-130 g (iodine)/100 g and comprising an unsaturated compound selected from the group consisting of C11-C22 fatty acids each having one carboxyl group and one double bond in its molecule and lower alkyl esters thereof and another unsaturated compound selected from the group consisting of C11-C22 fatty acids each having one carboxyl group and two to four double bonds in its molecule and lower alkyl esters thereof, and reducing the carboxyl groups (or lower alkyl ester groups in the case of the lower alkyl esters) of the obtained dimer and trimer molecules into hydroxyl groups.
    • 羟值为0〜134KOHmg / g的单体混合物,其可通过在分子中聚合选自由具有一个羧基和一个双键的脂肪酸组成的组中的不饱和化合物的混合原料获得,并且具有 11-22个碳原子,低级烷基酯与选自分子中具有1个羧基和2〜4个双键并且具有11-22个碳原子并且碘值范围为30的脂肪酸的不饱和化合物 至130g(碘)/ 100g,得到二聚体和三聚体,然后通过还原将所得二聚体和三聚体中存在的羧基(或低级烷基酯的情况下的低级烷基酯基)转化为羟基,得到 混合物,基本上由二聚体二醇和三聚体三醇组成,然后将二聚体二醇/三聚体三醇重量比为30/70至99/1的混合物进行酯化反应 与α,β-不饱和羧酸或与α,β-不饱和羧酸的低级烷基酯进行酯交换反应。 单体混合物可用于合成聚合物,例如用于光学应用的各种树脂材料。
