Processes for inhibiting scale produced during wet process phosphoric acid production by adding a scale-inhibiting amount of a reagent having a primary amine-containing polymer, or salt thereof, to one or more stages of a wet process phosphoric acid production stream are provided herein, wherein the primary amine-containing polymer includes an A mer according to Formula (I): ##STR00001## where R is H, C.sub.1-C.sub.6 alkyl, C.sub.2-C.sub.6 alkenyl, halide, or carboxyl; R.sup.1 is H, C.sub.1-C.sub.6 alkyl, or C.sub.2-C.sub.6 alkenyl; R.sup.2 is H or an A mer according to Formula (I) as herein defined; R.sup.3 is chosen from a direct bond or a C.sub.1-C.sub.12 alkyl, C.sub.2-C.sub.12 alkenyl, or a C.sub.6-C.sub.12 aryl group; and n is an integer chosen to provide a weight average molecular weight of the primary amine-containing polymer of at least 300 Daltons, and
wherein the percentage of primary amines in the polymer is from 30 mole % to 100 mole % based on the total percentage of mer units in the polymer.

To provide a blood cell separating agent and a blood cell separation method capable of separating blood cells in a short time from a sample containing blood cells collected for analysis. The problem is solved by a blood cell separating agent for analysis that contains a (co)polymer having at least one structural unit of a structure derived from a monoallylamine or a diallylamine having a secondary amino group or a secondary amide group or a structure that is an inorganic acid salt or an organic acid salt thereof.

A zwitterionic monomer and corresponding cyclopolymerized polyzwitterion () (PZ) (i.e. poly(Z-alt-SO.sub.2). Phosophonate ester hydroloysis in PZ gave a pH-responsive polyzwitterionic acid () (PZA). The PZA under pH-induced transformation was converted into polyzwitterion/anion () (PZAN) and polyzwitterion/dianion (=) (PZDAN).
