This invention provides chlorohydrocarbyloxy phosphonate oligomers, organophosphonate oligomers, and processes for the preparation of such oligomers. The chlorohydrocarbyloxy phosphonate oligomers can be represented by the formula (IV) where R I is a linear or branched hydrocarbylene group or oxygen- containing hydrocarbylene group, which hydrocarbylene group has about two to about twenty carbon atoms, or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; R is an alkyl group or an aromatic group; and n is a number from about 2 to about 20.

Cette invention propose des oligomères de chlorohydrocarbyloxy phosphonate, des oligomères d'organophosphonate et des procédés de préparation de tels oligomères. Les oligomères de chlorohydrocarbyloxy phosphonate peuvent être représentés par la formule (IV), dans laquelle R1 représente un groupe hydrocarbylène linéaire ou ramifié ou un groupe hydrocarbylène contenant de l'oxygène, lequel groupe hydrocarbylène possède environ deux à vingt atomes de carbone, ou un groupe hydrocarbylène ayant au moins un noyau cycloaliphatique ou aromatique; R2 représente un groupe alkyle ou un groupe aromatique; et n est un nombre d'environ 2 à 20.
