Embodiment Construction

[0012] I. Detailed description of the invention

[0013] In this specification, all percentages (%) shown are % by weight unless otherwise expressly stated. The abbreviation "phr" denotes parts by weight per hundred parts of elastomer (or the sum of the elastomers if several elastomers are present).

[0014] Furthermore, any numerical interval marked by the expression "between a and b" denotes a numerical range greater than "a" and less than "b" (i.e., excluding the limits a and b), while that marked by the expression "from a to b" Any numerical interval indicates a numerical range extending from "a" up to "b" (ie including the strict limits a and b).

[0015] The expression "composition based on" is understood in this description to mean that the composition comprises a mixture and / or in situ reaction product of the various components used, some of these basic components (e.g. elastomers, fillers or conventionally used Other additives of the rubber composition intended to ...

Abstract

The invention relates to a 1,3-dipolar compound having a nitrile oxide dipole and an anthracenyl group, which may or may not be substituted. Grafting a compound of this type allows synthesis of a diene polymer having conjugated pendant carbon-carbon double bonds.

Description

technical field [0001] The field of the invention is compounds intended to react with polymers comprising at least one carbon-carbon double bond, such as diene polymers, in order to graft substituted or unsubstituted anthracenyl groups onto the polymer chain. Background technique [0002] For grafting functional groups to diene polymers, it is known to use 1,3- Dipolar compounds. Examples of grafting are described, for example, in patent applications WO 2006 / 045088 and WO 2012 / 007441. The mechanism of the grafting reaction starts with the cycloaddition of the nitrile oxide dipole on the double bond, as described in the article "Nitrile Oxides, Nitrones and Nitronates in Organic Synthesis" (2nd edition, Wiley-Interscience, 2008). [0003] (Anthracene-9-ylmethylene)azol alkoxides of formula 1 are known to be characterized as 1,3-dipolar compounds bearing a nitrile oxide dipole and an anthracenyl group, but which do not contain at least one carbon - The reaction of polymers ...
