    • A cross-linked acrylic resin produced 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 with the essential ingredient. The resin, having a long aliphatic carbon chain, has a low specific gravity and an excellent heat resistance while enjoying a high transparency. Component (A): an ester prepared from (1) a diol (a) obtained by reducing a dimer of a C11-C22 unsaturated fatty acid and/or a diol (b) obtained by reducing a dimer of a lower alkyl ester of a C11-C22 unsaturated fatty acid and (2) acrylic or methacrylic acid. Component (B): an ester prepared from (1) a triol (pa) obtained by reducing a trimer of a C11-C22 unsaturated fatty acid and/or a triol (b) obtained by reducing a trimer of a lower alkyl ester of a C11-C22 unsaturated fatty acid and (2) acrylic or methacrylic acid.
    • 通过(共)聚合包含以下组分(A)和/或(B)的单体组合物作为必需成分并任选地含有包含可与基本成分共聚的单体的组分(C)而制备的交联丙烯酸树脂。 具有长脂肪族碳链的树脂在享受高透明性的同时具有低比重和优异的耐热性。 组分(A):由(1)通过还原C11-C22不饱和脂肪酸和/或二醇(b)的二聚体获得的(1)二醇(a)制备的酯,其通过将低级烷基酯的二聚体 C11-C22不饱和脂肪酸和(2)丙烯酸或甲基丙烯酸。 组分(B):由(1)通过还原C11-C22不饱和脂肪酸和/或三醇(b)的三聚体获得的三醇(pa)制备的酯,其通过还原三 C11-C22不饱和脂肪酸和(2)丙烯酸或甲基丙烯酸。
