Unsaturated compounds, in particular alkenyl ketones and cyano analogues, useful for polymerization with a variety of monomers to form photodegradable polymers, are formed by dehydrating a preformed liquid alkanol of the formula:
where X is an activating group for this dehydration reaction, preferably -CO- or -CN, in the presence of a solid dehydration catalyst, which may be acid resin, alumina or mixtures thereof. Apparatus for carrying out the method and novel products also are described.
不饱和化合物,特别是烯基酮类和氰基类似物,可与各种单体聚合形成光降解聚合物,其形成方法是将预制的液态烷醇进行脱水反应:
其中 X 是该脱水反应的活化基团,最好是 -CO- 或 -CN,在固体脱水催化剂(可以是酸性树脂、氧化铝或它们的混合物)存在下进行。此外,还介绍了实施该方法的装置和新型产品。
