摘要

It refers to graft copolymers, including at least three sequences with different chemical properties, one or more of which are fixed on solid particles, one or more underwater auditory sequences and one ovary, consisting of at least 1) 1-80% mass, preferably One or more sequences (s) anchored on 5% to 40% of solid particles, consisting of a carbonic, linear or aromatic hydrocarbon chain, including the basic acyclic nitrogen group, NH2, BH -, NHR o-nr2, CONH2, conhr2, conr2 (R is a radical (C1-C6) tar,Or become a member if you are not already a member.-Co-O -, s03h, including some cool groups,Its molecular weight is between 150 and 10000, preferably between 300 and 3000. The content of basic nitromonomer Lama in the anchor system is 5%, preferably 30%;(2) A mass of 10-90%, preferably 25-80%, is a sequence of one or more underwater properties, consisting of a carbonated, linear or separable chain, or of one or more groups, which may include-Yes, yesIf (o r) n (R) (2-N) (where R and R represent similar or different tar or arilos radicals, c1-c10yn = 0-2),It consists of a single unit with a solubility parameter less than 21.5 joules (1 / 2) / cm (1 / 2),Preferably less than 19 J (1 / 2) / cm (1 / 2, molecular weight between 250 and 10000, preferably between 500 and 3500; and (3) 10-90% hydrofluorooctane sulfonic acid sequence ovaries, preferably 15-70%, consisting of a group of - O -, linear or separable hydrocarbon chains,- Oh,
