  Acrylic acid esters are manufactured by reacting secondary or tertiary butyl or amyl alcohols with acrylic acid, preferably in the presence of a dehydrating agent, with an acrylic acid halide or with acrylic anhydride. In examples, acrylyl chloride is reacted in the presence of calcium carbonate with: (1) butanol-2 to produce sec.-butyl acrylate; (2) tert.-butyl alcohol to produce tert.-butyl acrylate; (3) pentanol-2 to produce sec.-amyl acrylate; (4) tert.-amyl alcohol to produce tert.amyl acrylate. Diethylcarbinol and methylisopropylcarbinol are also specified as starting materials. Polymerization products are manufactured by subjecting to polymerization, under the action of heat, irradiation or both, acrylic acid secondary or tertiary butyl or amyl esters, alone or in admixture with one another or with other substances, e.g. other esters of acrylic acid, esters of methacrylic acid, vinyl esters, ethers and ketones, acrylic and methacrylic acid halides, amides, nitriles and anhydrides, isoprene, butadiene or styrene. The polymerization may be effected in the presence of polymerization catalysts, e.g. organic or inorganic peroxides, oxygen or ozone, and may be carried out on the monomer alone, or dissolved in a solvent, which may be a non-solvent for the polymer, or suspended in a non-solvent, e.g. water, with or without emulsifying agents. The products may be obtained in the form of sheets, blocks or rods by effecting polymerization in a mould, preferably under pressure or in the presence of a terpene hydrocarbon to prevent the formation of bubbles. Useful articles may also be prepared from the polymers by moulding, turning or extrusion. The products may also be used for adhesives, electrical insulators or interlayers in laminated glass, or as coating-compositions, which may be obtained by polymerization in solution, with the addition, if desired, of pigments, fillers and colouring materials before, during or after polymerization. For moulding there may be added plasticizers, e.g. the ester of phthalic acid, camphor or acetone, whilst mould lubricants, e.g. mineral oils, neat's foot oil, stearic or oleic acid, may be used directly in the mould or incorporated in the polymer. The polymerization of the products of the examples above is described.

  丙烯酸酯是通过将二级或三级丁基或戊基醇与丙烯酸反应制造的，最好在脱水剂的存在下，与丙烯酸卤或丙烯酸酐反应。例如，丙烯酰氯在碳酸钙存在下与以下物质反应：(1) 2-丁醇生成丙烯酸仲丁酯；(2) 叔丁醇生成叔丁基丙烯酸酯；(3) 2-戊醇生成丙烯酸仲戊酯；(4) 叔戊醇生成叔戊基丙烯酸酯。另外，二乙基甲醇和甲基异丙基甲醇也被指定为起始原料。通过在热力、辐射或二者的作用下，对丙烯酸二级或三级丁基或戊基酯进行聚合制造聚合物产品，单独或与彼此或其他物质混合，例如丙烯酸酯的其他酯类、甲基丙烯酸酯、乙烯酯、醚和酮、丙烯酸和甲基丙烯酸卤、酰胺、腈和酐、异戊二烯、丁二烯或苯乙烯。聚合可以在聚合催化剂的存在下进行，例如有机或无机过氧化物、氧气或臭氧，并且可以在单体中进行，或溶解在溶剂中，该溶剂可以是聚合物的非溶剂，或者悬浮在非溶剂中，例如水，带有或不带有乳化剂。通过在模具中进行聚合，最好在压力下或在萜烯烃的存在下，以防止气泡的形成，可以获得产品的片材、块状或棒状形式。还可以通过模塑、车削或挤出从聚合物制备有用的制品。产品也可用于粘合剂、电绝缘体或夹层玻璃中间层，或作为涂料组合物，可以通过在溶液中聚合获得，如有需要，在聚合之前、期间或之后添加颜料、填料和着色材料。对于模塑，可以添加增塑剂，例如邻苯二甲酸酯、樟脑或丙酮，而模具润滑剂，例如矿物油、牛脚油、硬脂酸或油酸，可以直接用于模具中或并入聚合物中。上述示例产品的聚合过程如下所述。
