“…on iron or steel, and discussions on this subject continue. 139,140 Polyhexamethyleneguanidinium (PHMG) 7[(CH 2 ) 6 7NH7 C(=NH + )7NH] n 7 is also a polymeric cation worthy of note, as well as its salts synthesised by Antonik et al 141 and Tomin et al 142 At n = 10 ± 100, PHMG is a strong base and a biocide; its anticorrosion properties depend strongly on the counter-ion. PHMG phosphate mixed with small amounts of sodium nitrite and tetraborate provides good protection of steel in non-stirred aqueous solutions but is inefficient against scaling.…”

“…The high‐molecular‐weight counterparts, oligo/polymeric guanidines, have been known since the 1940 s. Because the free guanidine base is unstable in a condensed phase, polyguanidines are usually present in the protonated form as a salt, which possesses useful biocidal properties because of the quaternary nitrogen 8. Therefore, they are used as disinfectants,9 they are able to serve as ion exchangers,10 and they can be applied as an anti‐corrosion agent 11.

The first example of phantom ring-closing condensation polymerization for the synthesis of oligoguanidines is presented. A new oligoguanidine with a ring structure was achieved in one step by the condensation reaction of a triamine, like diethylenetriamine, with guanidine hydrochloride. The condensation reaction proceeded by selective ring-closure towards the formation of five-membered rings in the oligomer backbone. The resulting polymer repeat unit structure was different from the starting monomers (phantom polymer) and was formed by elimination of three molecules of ammonia per repeat unit. The inter-, intra-, and inter-molecular reaction sequences led to the new structure as proved by different spectroscopic techniques (atmospheric pressure chemical-ionization mass spectrometry, and one-dimensional and two-dimensional homo- and heteronuclear correlation NMR experiments) as well as supported by quantum chemical investigations. Preliminary results regarding antibacterial use of the resulting oligoguanidine were also promising and showed its effect within 15-30 min as an antibacterial material.

The color stabilization of antimicrobial blends was studied by using poly(hexamethylene guanidine) phosphate (PHMG) as a highly efficient biocidal and nontoxic agent. The Taguchi method was used to determine the optimum conditions for the blending of PHMG in polypropylene (PP) matrix. To improve the yellowing phenomena, two kinds of stabilizer were used together: tetrakis[methylene(3,5-di-t-butyl-4-hydroxyhydrocinnamate)](IN1010) from phenol and tris(2,4-di-t-butylphenylphosphite) (IF168) from phosphorus. According to blend composition and mixing condition, six factors were chosen, with five levels being set for each factor. The orthogonal array was selected as the most suitable for fabricating the experimental design, L25, with 6 columns and 25 variations. Thesmaller-the-better was used as an optimization criterion. The optimum conditions for these parameters were 10 phr for PHMG, 2 phr for IN1010, 1 phr for IF168, 10 min for mixing time, 210 o C for mixing temperature, and 30 rpm for rotation speed. Under these conditions, the yellowness index of the blend was 1.52. The processibility of the blends was investigated by Advanced Rheometric Expansion System (ARES). The blend with 0.5 w% PHMG content, diluted with PP, exhibited an antimicrobial characteristic in the shake flask method.
