  Additives suitable for improving the flow and/or depressing the cloud point of crude oils, lubricating oils and especially fuel oils are polymers containing defined alkyl groups of at least 8 carbon atoms chain length. Such polymers are either (a) of a mixture of monomers having only two alkyl groups one being at least 3 carbon atoms longer than the other or (b) of a mixture of monomers having only three alkyl groups each differing by at least 3 carbon atoms and the middle alkyl group being half the combined length of the other two. Alternatively, the polymer may be derived from a monomer having the two defined alkyl groups (a) or the three defined alkyl groups (b).

  适用于改善原油、润滑油，特别是燃料油的流动性和/或降低浊点的添加剂是含有至少 8 个碳原子链长的确定烷基的聚合物。这种聚合物可以是 (a) 单体的混合物，其中只有两个烷基，其中一个比另一个至少长 3 个碳原子；或者 (b) 单体的混合物，其中只有三个烷基，每个烷基至少相差 3 个碳原子，中间的烷基是另外两个烷基总长度的一半。或者，聚合物可以由具有两个定义的烷基（a）或三个定义的烷基（b）的单体衍生而来。

  In the production method of the present invention, an emulsion including a copolymer with a glass transition temperature (Tg) of -50 to 20°C is obtained by the emulsion polymerization of a monomer group including a monomer A that is a (meth)acrylic acid alkyl ester (where the alkyl group is an open chain group with 1 to 20 carbon atoms or a cyclic group with 5 to 20 carbon atoms) as the main monomer and a monomer B having a carbon-carbon double bond and a nonionic hydrophilic group such as a polyoxyalkylene group, an amide group, and a hydroxyl group. Liquid crystals are dispersed in this emulsion, which is applied onto a conductive film-coated substrate. Another conductive film-coated substrate is laminated thereto, and thus a liquid crystal light control device is obtained. A monomer C having a carboxyl group and/or an amino group and a carbon-carbon double bond may be used in combination with a crosslinking agent so that a crosslinked structure is introduced into the copolymer. The present invention provides a liquid crystal light control device in which the transparency with a voltage applied and the shielding property with no voltage applied are compatible at high level.

  在本发明的生产方法中一种包括玻璃化转变温度（Tg）为 -50 至 20°C 的共聚物的乳液，是由包括作为主单体的（甲基）丙烯酸烷基酯（其中烷基是具有 1 至 20 个碳原子的开链基团或具有 5 至 20 个碳原子的环状基团）的单体 A 和具有碳碳双键和非离子亲水基团（如聚氧烷基、酰胺基和羟基）的单体 B 的乳液聚合而成。液晶分散在这种乳液中，然后涂在涂有导电薄膜的基底上。将另一种涂有导电薄膜的基底层压在上面，就得到了液晶光控制装置。具有羧基和/或氨基以及碳碳双键的单体 C 可与交联剂结合使用，从而在共聚物中引入交联结构。本发明提供了一种液晶光控制装置，在该装置中，加电压时的透明性和不加电压时的屏蔽性在高水平上兼容。
