    • Improved flame retardant latex coatings are disclosed which comprise copolymers of ring-halogenated aromatic monomer units and alkyl acrylate/methacrylate monomer units, and which may additionally include at least one other monomer. In a first embodiment, the coatings include ring-brominated aromatic monomer units and alkyl acrylate and/or alkyl methacrylate monomer units. In a second embodiment, the coatings include these first two types of monomer units and further include third monomer units from unsaturated esters of saturated carboxylic acids, halogen-free aromatic monomers or unsaturated carboxylic or dicarboxylic acid monomers. In a third embodiment, the coatings include four monomer units, namely ring-brominated aromatic monomer units, alkyl acrylate/methacrylate monomer units, halogen-free aromatic monomer units and unsaturated carboxylic or dicarboxylic acid monomer units. In one aspect, the halogenated aromatic monomers are present in an amount to provide from 7 to 20 weight percent bromine in the final latex coating. In another aspect, the halogenated aromatic monomers include polybrominated monomers, particularly to provide monomers having an average of at least about 1.5 bromines per monomer unit. The coating polymers have glass transition temperatures in the -30.degree. C. to 30.degree. C. range and are useful, for example, for coating, paint, adhesive, sealant and non-woven binder applications.
    • 公开了改进的阻燃胶乳涂层,其包含环 - 卤代芳族单体单元和丙烯酸烷基酯/甲基丙烯酸烷基酯单体单元的共聚物,并且其可另外包含至少一种其它单体。 在第一个实施方案中,涂层包括环溴化芳族单体单元和丙烯酸烷基酯和/或甲基丙烯酸烷基酯单体单元。 在第二实施方案中,涂层包括这些前两种类型的单体单元,并且还包括来自饱和羧酸的不饱和酯,无卤素芳族单体或不饱和羧酸或二羧酸单体的第三单体单元。 在第三实施方案中,涂层包括四个单体单元,即环溴化芳族单体单元,丙烯酸烷基酯/甲基丙烯酸酯单体单元,无卤素芳族单体单元和不饱和羧酸或二羧酸单体单元。 在一个方面,卤代芳族单体的存在量为最终胶乳涂料中的7至20重量%的溴。 另一方面,卤代芳族单体包括多溴单体,特别是提供每单体单元平均具有至少约1.5个溴的单体。 涂层聚合物的玻璃化转变温度在-30摄氏度到30摄氏度的范围内,并且可用于例如涂料,油漆,粘合剂,密封剂和无纺粘合剂应用。
