New dendrimers with phosphonic terminal groups used in surface treatment compositions and as anti-corrosion, lubricant, anti-scale and fire retardant agents

摘要

New dendrimers with monophosphonic terminal groups. The dendrimers of generation 0-12 consist of a central nucleus of valency 3-8, optionally arborescence generation chains around the nucleus, an intermediate chain around the nucleus or at the end of each generation chain and a terminal chain at the extremity of each intermediate chain. The terminal group is of formula - P(=O)(OX) 2. X : methyl, H, M +; M +cation.
