    Abstract: An optical fiber coating composition that includes an acrylic copolymer. The acrylic copolymer is a block copolymer that includes two or more acrylic blocks. The two or more acrylic blocks differ in glass transition temperature (Tg). The acrylic copolymer may include an acrylic block with a Tg above 50° C. and an acrylic block with a Tg below 0° C. Representative monomers from which the repeat units of the acrylic blocks are derived include alkyl(meth)acrylates. In one embodiment, the acrylic copolymer includes an acrylic block with repeat units derived from methylmethacrylate and an acrylic block derived from butylacrylate. The acrylic copolymer lacks urethane groups, lacks urea groups, lacks radiation-curable groups, and is otherwise unreactive with other components in the coating composition. The acrylic copolymer features high solubility in common acrylate-based radiation-curable coating compositions and can be provided at high concentrations in acrylate-based coating compositions.

    Abstract translation: 包括丙烯酸共聚物的光纤涂料组合物。 丙烯酸共聚物是包含两个或更多个丙烯酸嵌段的嵌段共聚物。 两种或多种丙烯酸酯嵌段的玻璃化转变温度(Tg)不同。 丙烯酸共聚物可以包括Tg高于50℃的丙烯酸嵌段和Tg低于0℃的丙烯酸嵌段。衍生出丙烯酸嵌段的重复单元的代表性单体包括(甲基)丙烯酸烷基酯。 在一个实施方案中,丙烯酸共聚物包括具有衍生自甲基丙烯酸甲酯的重复单元的丙烯酸嵌段和衍生自丙烯酸丁酯的丙烯酸嵌段。 丙烯酸共聚物缺乏氨基甲酸酯基团,缺少尿素基团,缺少可辐射固化的基团,并且与涂料组合物中的其它组分无反应。 丙烯酸共聚物在基于丙烯酸酯的可辐射固化涂料组合物中具有高溶解度,并且可以以高浓度提供丙烯酸酯基涂料组合物。

    Abstract: A compound of formula (I), formula (II), or a combination thereof, and salts thereof is described. Each A may be independently an optionally substituted conjugated species or an optionally substituted aromatic species. Each R may be independently an optionally substituted C1-C40 linear alkyl chain, an optionally substituted branched alkyl chain, an optionally substituted alkyl chain containing heteroatoms, substituted alkyl chains, or H. Each R2 may be independently an optionally substituted C1-C40 linear alkyl chain, an optionally substituted branched alkyl chain, an optionally substituted alkyl chain containing heteroatoms, substituted alkyl chains, H, or part of a cyclic boronate ester with an other R2. Each n may be independently less than or equal to 3 and greater than or equal to 1. Each x may be independently less than or equal to 3.
