  A water-developable flexographic printing plate is made by applying a layer of a photosensitive composition to a backing. The photosensitive composition includes an ABA triblock polymer, where B is a conjugated diene monomer, typically isoprene or butadiene, and A is an acrylate monomer, typically t-butylmethacrylate.

  将一层感光组合物涂在衬底上，就制成了水显影柔性印版。感光组合物包括 ABA 三嵌段聚合物，其中 B 是共轭二烯单体，通常是异戊二烯或丁二烯，A 是丙烯酸酯单体，通常是甲基丙烯酸叔丁酯。

  The present invention is an improvement upon the known method of anionically polymerizing monomers by contacting the monomers with an anionic polymerization initiator which is an organo-substituted alkali metal compound. The improvement comprises decreasing the viscosity of the polymer cement by adding at least 0.01 equivalent of a metal alkyl compound per equivalent of alkali metal initiator if the metal alkyl is added before or at the beginning of polymerization. If the metal alkyl is added during the polymerization or after but before the living polymer is terminated, then at least 0.01 equivalent of the metal alkyl compound per equivalent of living polymer chain ends is should be used. The alkyl groups of the metal alkyl are chosen such that they do not exchange with the organo substituents of the alkali metal, which can be the living polymer chain ends or the organo substituents of the initiator. To avoid this undesired exchange reaction, the alkyl groups of the metal alkyl compound are selected to be more basic and/or less bulky or both than the organo substituents of the alkali metal compound.

  本发明是对已知的阴离子聚合单体的方法的改进，该方法是将单体与有机取代碱金属化合物的阴离子聚合引发剂接触。改进措施包括：如果金属烷基是在聚合之前或聚合开始时加入的，则每当量碱金属引发剂中至少加入 0.01 当量的金属烷基化合物，以降低聚合物水泥的粘度。如果金属烷基是在聚合过程中加入，或在聚合之后但在活聚合物终止之前加入，则每当量活聚合物链端至少应使用 0.01 当量的金属烷基化合物。金属烷基的烷基应选用不会与碱金属的有机取代基（可以是活聚合物链端或引发剂的有机取代基）发生交换的烷基。为避免这种不希望发生的交换反应，金属烷基化合物的烷基应选为比碱金属化合物的有机取代基碱性更强和/或体积更小，或两者兼而有之。

  Disclosed is a process for preparing hydrogenated conjugated diene block copolymers having the steps of (a) charging a solvent, a microstructure control agent, and an alkenyl aromatic hydrocarbon monomer into a first reactor forming an admixture of solvent, a microstructure control agent, and an alkenyl aromatic hydrocarbon monomer wherein the concentration of the microstructure control agent is from about 5 to about 10 weight percent; (b) titrating the admixture of solvent, microstructure control agent, and alkenyl aromatic monomer using an anionic polymerization initiator to form a living polymer; (c) allowing sufficient time for the living polymer to react with and incorporate the alkenyl aromatic monomer; (d) charging a conjugated diene monomer into the first reactor; (e) allowing sufficient time for the living polymer to react with and incorporate the conjugated diene monomer to form a living block copolymer; and (f) hydrogenating the living block copolymer to form a hydrogenated conjugated diene block copolymer. This single reactor process allows for the use of a microstructure control agent.

  Disclosed is a process for preparing polymers and copolymer blocks of conjugated dienes with varying amounts of branching comprising the use of a microstructure control agent and a microstructure control agent deactivant. The polymerization can be started with or without a microstructure control agent. At some point in the polymerization prior to the completion of the addition of the conjugated diene to the polymer, the microstructure control agent can be deactivated, either partially or completely, resulting in a polymer or copolymer block having a region of less branching adjacent to a region of more branching. Preferred microstructure control agent deactivants are metal alkyls such as triethyl aluminum.

  本发明公开了一种制备具有不同支化量的共轭二烯聚合物和共聚物嵌段的工艺，包括使用一种微结构控制剂和一种微结构控制剂失活剂。聚合可以在使用或不使用微结构控制剂的情况下开始。在聚合物中共轭二烯添加完成之前的聚合过程中，微结构控制剂可以部分或完全失活，从而使聚合物或共聚物嵌段在分支较多的区域附近形成分支较少的区域。首选的微结构控制剂灭活剂是金属烷基，例如三乙基铝。

  The present invention is an improvement in a method of anionically polymerizing monomers by contacting them with an anionic polymerization initiator which is an organo-substituted alkali metal compound in the presence of low amounts of an accelerator/promoter and/or a highly active microstructure modifier. The improvement comprises adding from 0.1 to 1.0 equivalents of a metal alkyl compound per equivalent of alkali metal initiator wherein alkyl groups of the metal alkyl compound are chosen so that they will not exchange with the organo substituents of the alkali metal compound. The preferred initiator for use herein is the sec-butyl lithium adduct of diisopropenyl benzene and the preferred metal alkyl is triethyl aluminum.
