The invention relates to a copolymer and a substrate having a surface, at least one part of which is coated with an epilame agent comprising at least one compound in the form of a copolymer comprising V units, N units, optionally at least one M unit, and optionally at least one P unit, linked by covalent bonds by their main chains, wherein
wherein W, X, Y, Z are spacer arms, T is a tracer group arranged to determine the concentration of epilame agent in an epilame-coating bath, L is a halogenated, preferably fluorinated, C1-C20 carbon moiety, A is a substrate anchoring moiety, Q is H, CH3, or a hydrocarbon chain different from T.
The invention also concerns a method for coating such a substrate with epilame, said method comprising a step of checking the concentration of epilame agent in the epilame-coating bath by means of the tracer group and if necessary, a step of readjusting the concentration of epilame agent in the epilame-coating bath.
本发明涉及一种共聚物和一种具有表面的基材,其表面至少有一部分涂有表胺剂,表胺剂由至少一种共聚物形式的化合物组成,共聚物包括 V 单元、N 单元、可选的至少一个 M 单元和可选的至少一个 P 单元,它们通过共价键由主链连接,其中
其中,W、X、Y、Z 是间隔臂,T 是示踪基团,用于确定附着剂涂层浴中的附着剂浓度,L 是卤化的(最好是氟化的)C1-C20 碳分子,A 是基质锚定分子,Q 是 H、CH3 或与 T 不同的烃链。
本发明还涉及一种给这种基底涂上表焰剂的方法,该方法包括通过示踪基团检测表焰剂涂层槽中表焰剂的浓度,必要时重新调整表焰剂涂层槽中表焰剂的浓度。
