Definitions
- the present invention relates to an alkoxyamine composition having better storage stability, in particular in the presence of monomers and / or of solvent.
- the present invention also relates to the use of these alkoxyamine compositions for the synthesis of polymers and copolymers, as well as the polymers obtained with these new alkoxyamine compositions.
- Alkoxyamines are molecules which allow controlled radical polymerization of monomers having double bonds (vinyl, styrenic, (meth) acrylic, etc.). It is thus possible to access the synthesis of block copolymers.
- the alkoxyamines must contain a minimum of solvent to preserve the character of acceptable reactivity and to be considered stable.
- the reactivity of a given alkoxyamine in the presence of monomer under polymerization conditions is assessed by measuring the kinetics of polymerization, for example measuring the conversion rate over time. A polymerization made with an alkoxyamine freshly removed from the refrigerator is thus compared to a polymerization made with the same alkoxyamine but having remained for several days in a solvent.
- an alkoxyamine-solvent composition the solvent possibly being one monomer or more monomers, is all the more stable the lower the amount of solvent, that is to say that it retains its reactive nature.
- the various industrial manufacturing processes and stages of alkoxyamines always lead to the presence of solvent together with the alkoxyamine at the end of the polymerization process.
- the Applicant has thus found that beyond a certain amount of solvent, the alkoxyamine could no longer be considered as a chemical reagent useful industrially for carrying out a controlled or uncontrolled radical polymerization.
- the invention relates to a composition of at least one alkoxyamine and at least one solvent in a closed storage container, which may or may not be transportable, the solvent possibly being polar or non-polar, or even consisting of one or more monomers, the said solvent being present in quantities of between 0 and 65% by mass relative to the alkoxyamine or to the alkoxyamines, 0 excluded.
- alkoxyamine can be used in the context of the invention.
- the Applicant has thus demonstrated that with two different alkoxyamines, the stability character degrades in the presence of solvent over time.
- the alkoxyamines can be polyalkoxyamines (that is to say multifunctional alkoxyamines) but also monofunctional or multifunctional macroalkoxyamines, that is to say alkoxyamines resulting from an addition reaction. alkoxyamine on one or more monomers.
- the preferred alkoxyamines are those in which the nitroxide (also called controller fragment) is chosen from the following:
- nitroxide is the preferred nitroxide.
- alkoxyamines all the alkoxyamines associated with the preceding nitroxides can be concerned with the invention and in particular N- (2-methylpropyl) -N- (l-diethylphosphono-2, 2-dimethylpropyl) -O- (2 -carboxyprop-2-yl) hydroxylamine.
- the invention also relates to a composition of at least one alkoxyamine and at least one solvent, the solvent being able to be polar or apolar, or to be constituted by one or more monomers, the said solvent being present in amounts of between 0 and 65% by mass relative to the alkoxyamine or to the alkoxyamines, 0 excluded.
- composition of at least one alkoxyamine and at least one solvent optionally in a closed and transportable storage container or not contains between 0 and 65% by mass of solvent, 0 excluded, and preferably less than 10%, so preferred less than 1% and more preferably less than 0.5%.
- the present invention also relates to the use of these alkoxyamine compositions for the synthesis of polymers and copolymers, as well as the polymers obtained with the alkoxyamine compositions object of the invention, whether they are homopolymers, copolymers statistics, block copolymers (diblocks, triblocks, multiblocks).
- the solvent can be of any type, polar or nonpolar, alone or in mixtures.
- solvent is meant a solvent whose solubility of alkoxyamines can range up to 70% by mass in said solvent.
- alkanes linear or not, aromatic solvents such as toluene or xylenes, alcohols, ketones or even esters.
- the reactivity is considered acceptable when the alkoxyamine stored in the presence of solvent for more than 4 days, the polymerization kinetics of a given monomer at a given polymerization temperature with this composition is not further slowed down 5% in conversion value.
- the monomers which may form part of the composition of the invention may be any type of monomer carrying a double bond, provided that it is a solvent for the alkoxyamine.
- the following monomers vinyl, vinylidene, diene, olefinic, allyl or (meth) acrylic monomers.
- This monomer is chosen more particularly from vinylaromatic monomers such as styrene or substituted styrenes in particular alpha-methylstyrene, silylated styrenes, acrylic monomers such as acrylic acid or its salts, alkyl acrylates, of cycloalkyl or aryl such as methyl, ethyl, butyl, ethylhexyl or phenyl acrylate, hydroxyalkyl acrylates such as 2-hydroxyethyl acrylate, etheralkyl acrylates such as 2-methoxyethyl acrylate, alkoxy- or aryloxy-polyalkylene glycol acrylates such as methoxypolyethylene glycol acrylates, ethoxypolyethylene glycol acrylates, methoxypolypropylene glycol acrylates, methoxy- polyethylene glycol-polypropylene glycol acrylates or mixtures thereof or mixtures thereof aminoalkyl such as 2-
- this can be a container of any shape, any capacity and of any kind, but preferably it is a cylindrical barrel or a bottle d '' 200 liters plastic capacity.
- the closed and transportable or non-transportable storage container can also be a plastic bag.
- the closed and transportable or non-transportable storage container can also be a metal storage capacity, for example in a manufacturing workshop.
- the alkoxyamine used is N- (2-methylpropyl) -N- (1- diethylphosphono-2, 2-dimethylpropyl) -O- (2-carboxyprop-2- yl) hydroxylamine, the structural formula of which is as follows:
- Blocbuilder ® It is available from Arkema under the name Blocbuilder ® .
- Kinetic monitoring of a polymerization of butyl acrylate is carried out in bulk and in the solvent phase (30% by mass in toluene at 122 ° C.) with Blocbuilder ® freshly removed from the refrigerator.
- Blocbuilder ® The quantity of Blocbuilder ® is fixed at 1.57% by mass relative to the butyl acrylate.
- the conversions are followed by measuring the dry polymer extract converted by evaporation of the unreacted butyl acrylate in a vacuum oven at 130 ° C. The conversion results are given in table 1 below and correspond to test 1.
- Blocbuilder ® is left in toluene at different concentration and in ethanol for 4 days in a closed container at 20 ° C.
- An alkoxyamine macromolecular monofunctional, product of the addition of butyl acrylates entity 15 on the BlocBuilder ® was also tested. It is called Blocbuilder ® Abul5 and its synthesis can be undertaken in a simple manner according to the protocol described in EP1526138.
- Example 2 Each solution of the tests of Example 2 is used to carry out a polymerization of butyl acrylate according to the protocol of Example 1 with kinetic monitoring by measuring the level of solid over time.
- the molar proportion of alkoxyamine is identical in all the tests.
