  The present invention is directed to a process for the preparation of (meth)acrylates of halogenated alcohols by direct esterification of said alcohols with (meth)acrylic acid (chloride) wherein at least 2,6-substituted pyridine derivative is used as a polymerization inhibitor at room temperature or lower. Suitable at least 2,6-substituted pyridine derivatives are 2,6-lutidine, 2,4,6-collidine or 2,6-di-tert.butyl-4-methyl pyridine. With the halogenated (meth)acrylate esters prepared with the process according to the invention, very pure homo- and copolymers can be prepared, resulting in polymers having a low optical loss of 0.1 dB/cm or lower at 1300 nm and lower than 0.4 dB/cm at 1550 nm.

  本发明涉及一种通过将卤代醇与（甲基）丙烯酸（氯化物）直接酯化来制备（甲基）丙烯酸酯的方法，其中至少使用一种2,6-取代吡啶衍生物作为聚合抑制剂，温度为室温或更低。适用的至少2,6-取代吡啶衍生物包括2,6-吡啶、2,4,6-考林或2,6-二叔丁基-4-甲基吡啶。 通过根据本发明的方法制备的卤代（甲基）丙烯酸酯，可以制备非常纯净的同聚物和共聚物，从而得到在1300纳米处光学损耗低至0.1 dB/cm或更低，在1550纳米处低于0.4 dB/cm的聚合物。
