Definitions
- New monomers with a dilactonic cycle and corresponding polymers.
- the invention relates to new monomers with a dilactonic cycle, as well as the corresponding polymers, their preparation and the materials containing them.
- Biocompatible and / or biodegradable polymers are also of great interest in the production of packaging products for products manufactured in industry, including the food industry, due to the ever increasing constraints linked to the Environmental Protection.
- biodegradable polymers based on non-toxic products it is desirable to use raw materials of agricultural, plant or animal origin, which present in particular the advantage of avoiding complex chemical syntheses, when it is desired obtain products degradable into non-toxic compounds, and in particular degradable into natural products.
- the products of agricultural origin the dares and their derivatives constitute an abundant and relatively inexpensive raw material.
- their use poses several problems, in particular the presence of numerous hydroxyl groups which are all capable of reacting and which therefore make it difficult to obtain defined products.
- R is the residue of an acid R-CHOH-C0 2 H derived from a ose, the functional groups contained in R being optionally substituted, and X represents a group -C (R 1 ) (R2) - or
- the invention also relates to polymers (homopolymers and copolymers) obtained using a monomer of formula III and optionally other comonomers. These polymers are those which contain units of formula I
- the aryl groups including those present in the aralkyl groups, denote in particular optionally substituted phenyl groups, and the alkyl groups denote in particular those having from 1 to 4 carbon atoms.
- the polymers of the invention are in particular linear polymers having average molar masses which can range, for example, from 1000 to 3 million approximately.
- the acids derived from an ose can be chosen, for example, from those derived from an ose having from 3 to 7 carbon atoms, and in particular from 4 to 6 carbon atoms, including glyceraldehyde, erythrosis, threose , lyxose, xylose, arabinose, ribose, glucose, galactose and mannose, in the form of their various isomers, and in particular those of the D series. aldonic, uronic and aldaric acids.
- aldonic acids mention may be made in particular of gluconic, mannonic, galactonic, ribonic, arabinonic, xylonic and erythronic acids.
- uronic acids mention may be made, for example, of glucuronic, galacturonic and mannuronic acids.
- aldaric acids tartronic acid and tartaric, glucaric, galactaric and xylaric acids are particularly mentioned.
- the acid derived from an ose is an aldonic acid, that is to say an acid of formula: H- (CHOH) m -C0 2 H in which m is an integer which can vary in particular from 2 to 6, the monomers of formula III are in particular those for which R represents an H- (CHOH) - t group or a corresponding group in which one or more hydroxyl groups are substituted;
- 0 CH- (CHOH) F-1 - or a corresponding group in which one or more hydroxyl groups are substituted;
- the monomer of formula Illa can also be, as is easily understood, in the form of a derivative comprising the dilactonic ring at each of its ends; in other words, in this case, R can represent a group of formula VI:
- q is an integer which can vary for example from 2 to 5.
- monomers of formula Illa comprising two dilactonic rings, have the advantage of constituting not only polymerization agents, but also, because of their bifunctional nature , crosslinking agents, which can crosslink in particular any polymer capable of reacting with a lactone, that is to say any polymer comprising mobile proton functions such as alcohol, acid functions (carboxylic, hemisulfate, monophosphate, diphosphate, sulfonic ) or primary or secondary amino functions.
- a protected group denotes a group which is reversibly or irreversibly modified, by substitution (in this sense, "protected” and “substituted” are here synonymous), the substituent being able to be a protective group in the usual sense or a group which, in addition to its protective role (temporary or not), is capable of bringing advantageous properties such as a pharmaceutical or cosmetological activity, a coloring power, a fluorescent activity cence, phytosanitary properties, in particular a pesticidal effect (for example insecticide), thermo-reversible properties, thermosensitive or photosensitive activity, etc.
- the expression “protecting group” therefore designates, in general, such substituents. Groups capable of temporarily or not protecting hydroxyl groups are known. We can quote for example:
- - ethers such as methyl, vinyl, benzyl, trityl, tetrahydrofuranyl, p-nitrobenzyl, 3, 4-dethmethoxybenzyl, 2-methoxyethoxymethyl ethers; or alternatively silyl ethers such as trialkylsilyl ethers, alkyldiphenylsilyl ethers, alkylphenylalkoxysilyl ethers, which can be obtained by the action on an alcohol of a corresponding silyl halide,
- esters in particular sulfonates, including alkylsulfonates, phosphates, including dialkylphosphates, borates, acetates, benzoates, pivalates, sulfates, nitrates, etc.,
- - cyclic acetals obtained by the action of a carbonyl compound or one of its derivatives (in particular acetone, benzaldehyde and formaldehyde) on two hydroxyl groups carried by two carbons located one relative to the other in the ⁇ or ⁇ position on the compound carrying the hydroxyls to be protected, which leads to cyclic acetals containing in particular an isopropyl group dene, benzylidene or methylene connecting the two hydroxyls considered; for example, by reaction of gluconic acid with paraformaldehyde, a diacetal is obtained 2.4-3.5 and by reaction with acetone, a diacetal is obtained 3.4-5.6.
- a carbonyl compound or one of its derivatives in particular acetone, benzaldehyde and formaldehyde
- the two hydroxyls in alpha of the carboxylic groups can be temporarily protected by formation of a cyclic acetal, for example with dimethoxytoluene.
- the remaining unprotected hydroxyl can then be protected using 2-methoxyethoxymethyl chloride to form the corresponding ether.
- the two hydroxyls can then be released into alpha by catalytic hydrogenation.

It is possible to crosslink in particular using the products of formula Illa derived from an aldaric acid having two lactonic cycles, as mentioned previously.
