| abstract |
The invention concerns an epoxidized trialkylammonium salt characterised in that it is selected among salts of general formula (I), wherein: R represents a (CH2)n-A-NH-(CH2)n'-N<+>R1R2R3 group wherein A represents a -CO- or CH2- group; n' and n range between 1 and 20, with n+n' not less than 10; R1, R2 and R3 are C1-C20 alkyl or mono-hydroxyalkyl groups, linear or branched, identical or different; X represents counterion. The invention also concerns a synthesis method for said salts, the use of said salts as chemical grafting agents, a chemical grafting method for substrates and the resulting biocidal and/or bacteriostatic substrates. |
