Propenyl ether monomers of formula V A(OCH.dbd.CHCH.sub.3).sub.n wherein n is an integer from one to six and A is selected from cyclic ethers, polyether and alkanes are disclosed. The monomers are readily polymerized in the presence of cationic photoinitiators, when exposed to actinic radiation, to form poly(propenyl ethers) that are useful for coatings, sealants, varnishes and adhesives. Compositions for preparing polymeric coatings comprising the compounds of formula V together with particular cationic photoinitiators are also disclosed, as are processes for making the monomers from allyl halides and readily available alcohols. The process involves rearranging the resulting allyl ethers to propenyl ethers.
公开了公式V A(OCH.dbd.CHCH.sub.3).sub.n的丙烯醚单体,其中n为1至6的整数,而A选择自环状醚,聚醚和脂肪族化合物。当暴露于光致辐射下时,在阳离子光引发剂的存在下,这些单体很容易聚合形成有用于涂料,密封剂,清漆和粘合剂的聚丙烯醚。还公开了包括公式V化合物和特定阳离子光引发剂的组合物,用于制备聚合物涂层,以及从烯丙基卤化物和易得到的醇制备单体的过程。该过程涉及将得到的烯丙基醚重排为丙烯醚。
