据美国联邦公报消息，10月5日美国环保署发布条例，豁免丙烯酸-丙烯酸丁酯-苯乙烯共聚物（Acrylic acid-butyl acrylate-styrene copolymer）。
Momentive Performance Materials公司向美国环保署提交本次豁免申请。经过评估，美国环保署认为，没必要制定丙烯酸-丙烯酸丁酯-苯乙烯共聚物在食品与饲料中的限量。
部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, polymer with butyl 2-propenoate and ethenylbenzene, also known as acrylic acid-butyl acrylate-styrene copolymer, when used as an inert ingredient in a pesticide chemical formulation. Momentive Performance Materials submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 2-propenoic acid, polymer with butyl 2-propenoate and ethenylbenzene on food or feed commodities.
