  The present invention involves a new synthesis route for the formation of lactylates. The method comprises reacting a dilactide with a compound comprising a hydroxy group. This reaction is preferably carried out in the presence of a cation or other source of alkalinity. Preferred compounds comprising a hydroxy group include any fatty acid and fatty acid alcohol (particularly C 1 -C 26 fatty acid chains). Preferred cations include cations of Group I and II metals, with sodium, calcium, and potassium cations being particularly preferred. The inventive reactions proceed much more rapidly than prior art lactylate synthesis reactions, and can be used to form 1-, 2-, 3-, 4-, and 5-lactylates.

  本发明涉及一种用于合成乳酰酸盐的新合成途径。该方法包括将二乳酸酯与含有羟基的化合物发生反应。该反应最好在存在阳离子或其他碱性来源的情况下进行。含有羟基的化合物包括任何脂肪酸和脂肪醇（尤其是碳链为C1-C26的脂肪酸链）。优选的阳离子包括I和II族金属的阳离子，其中特别优选的是钠、钙和钾阳离子。这种创新的反应比现有技术中的乳酰酸盐合成反应快得多，并可用于形成1-、2-、3-、4-和5-乳酰酸盐。

• No-post-cure method of curing polyacrylate polymers

  公开号：EP0309794A2

  公开（公告）日：1989-04-05

  A no-post-cure method of curing polyacrylates having dual cure sites is accomplished with a two-part curing system or a combined one-part curing system. The two-part curing system consists of one or more metallic acid salts and an ammonium and/or phosphonium quaternary salt. The one-part curing system consists of an ammonium or phosphonium quaternary acid salt. The polyacrylate rubber must have both a halogen and a carboxyl cure site. The method consists of blending the curative with the polyacrylate rubber and heating the resultant com­position until the composition cures. Because the mixed composition is shelf stable, it is not necessary to immediately heat the composition to cure it. The method may optionally include the step of storing the mixed composition until it is desired to cure it.

  使用双组分固化体系或组合式单组分固化体系，可实现具有双重固化位点的聚丙烯酸酯的免后固化方法。双组分固化体系由一种或多种金属酸盐和一种铵和/或鏻季盐组成。单组分固化体系由铵或鏻季酸盐组成。聚丙烯酸酯橡胶必须同时具有卤素和羧基固化位点。该方法包括将固化剂与聚丙烯酸酯橡胶混合，然后加热所得组合物，直至组合物固化。由于混合后的组合物具有货架稳定性，因此无需立即加热组合物使其固化。该方法可选择包括储存混合组合物的步骤，直到需要固化为止。
• Polyacrylate polymers utilizing substituted urea retarder

  A dual cure site polyacrylate polymer is provided which utilizes an aliphatic or aryl substituted urea or thiourea as a retarder to inhibit scorch during processing. While the polymer utilizes a retarder, compression set characteristics are not harmed and in fact may be enhanced by the use of the retarder.

  本发明提供了一种双固化点聚丙烯酸酯聚合物，它利用脂肪族或芳基取代的脲或硫脲作为缓凝剂，以抑制加工过程中的焦烧。虽然这种聚合物使用了缓凝剂，但其压缩永久变形特性并不会受到损害，事实上，使用缓凝剂还可以增强这种特性。
