It is known that certain halogenated diphenyl ether compound have an excellent antimicrobial activity. These compound are therefore widely used, for example as active substances for the antimicrobial finishing of medical items and household articles, as detergent additive and in the hygiene sector, for example in soaps or dental hygiene products. Polymeric materials can be antimicrobially finished by incorporating halogenated diphenyl ether compound, the active substances being, as a result of their excellent migration properties, constantly conveyed to the surface of the corresponding material ("slow release"). For certain industrial applications, this effect is undesired since the long-ter effect of antimicrobially finished materials such as textiles, paper, plastics, cellulose sponges etc. is reduced at the same time.

100 NI of the compound of the formula (103) (in 96% ethanol) are poured into each well, and the plates are incubated at 37°C for about 24 hours.

The results are given in Table 2.

The results show that the compound of the formula (103) has excellent bacteriostatic activity.

ExamDle 10: Determination of the minimum inhibitorv concentration (MIC) of the compound of the formula (101): An agar incorporation test is carried out to determine the MIC: Medium: Nutrient agar as test agar for bacteria: Casein soybean flour peptone agar to cultivate the microorganisms 0.9% sodium chloride (pH 7.2) for obtaining the bacterium suspension Methyl Cellosolve as solvent Test bacteria Escherichia coli NCTC 8196 Pseudomonas aeruginosa CIP A-22 Serratia marcescens ATCC 14'756 Enterococcus faecium ATTC 10'541 Staphylococcus aureus ATCC 9144 Candida albicans ATCC 1 0'23q Procedure: The test substances are dissolve in methyl Cellosolve, and a dilution series of the compound of the formula (101) in agar are prepared.

After the cultures have been cultivated on casein soybean flour peptone agar, the cells are floated out using NaCI solution and adjusted to a density of about 106 CFU/ml (live bacterial count).

1 Nl of each bacterial suspension is dropped onto the agar plates containing the test substance, and the plates are then incubated at 37°C for 2 days. As controls, the bacterial suspensions are applied to agar plates without test substances. In order to exclude the solvent methyl Cellosolve having an influence on the growth properties, the bacterial suspensions are applied to agar plates containing methyl Cellosolve, but without test substance.

After the plates have been incubated, the growth of the bacteria on the test-substance-containing plates is compare with that on the control plates.

The minimum inhibitory concentration (MIC) is given as the lowest concentration which shows clear inhibition compare with the control.

The MIC values are given in the table below.

Examole 22: 10 grams of the compound of formula (102) is added into 45 grams of low density polyethylene (Escorene LL6301 XR, from Exxon) and 45 grams of low density polyethylene (Escorene LL6301 RQ, from Exxon). The mixture is tumble mixed for 10 minutes followed by addition into a 29mm twin-extruder to produce a master batch. The extrusion temperature is set at 180"C.

Example 23: 10 gram of the resulting master batch (contains 10% of compound of formula 102) in Example 22 is added into 90 grams of low density polyethylene pellets (Escorene LL6301 XR, from Exxon) and well mixed. The mixture is then charged into an injection moulding machine to produce low density polyethylene plates (10 x 20 cm, thickness 2mm).

The resulting low density polyethylene plates contain 1% of compound of formula (102). The plates are then cut into discs of 2 cm in diameter and tested for antimicrobial efficacy in agar diffusion test by using the same procedures as described in Example 8.

The results are listed in Table 4.
