Abstract: A crystallization method that comprises a step of providing a polyester comprising at least one 1,4:3,6-dianhydrohexitol unit, and a step of crystallizing this semi-crystalline polyester at a pressure of at least 600 mbar absolute. The method according to the invention makes it possible to strongly limit, or even eliminate, the phenomenon of polyester expansion during crystallization. Advantageously, the elimination of the expansion phenomenon through pressure conditions implemented according to the invention thus makes it possible to dispense with obtaining very fragile empty spheres that break when agitated and thus cause the formation of undesirable fine particles.

Abstract: One subject of the present invention is the use of a combination of a polyol (i) consisting of 12 carbon atoms and of a polyol (ii) consisting of 4 to 6 carbon atoms, as protein stabilizer. Another subject of the present invention is protein compositions comprising such a combination. A final subject of the present invention is a process for preparing protein compositions using such a combination.

Abstract: The invention relates to a composition comprising: at least one aliphatic polyester (A) comprising diols containing at least ethylene glycol, 1,4-butanediol or mixtures thereof and diacids containing at least succinic acid, adipic acid or mixtures thereof; at least one starch (B); at least one organic plasticiser (C) for starch; optionally, an additional polyester or a mixture of additional polyesters (D) different from polyester (A). The composition is characterised in that it also comprises citric acid (E), the amount by weight of citric acid varying between 0.01 and 0.45 parts per 100 parts of the total dry weight of (A), (B), (C) and (D).

Abstract: The invention relates to the field of polymers and concerns a method for the crystallization of polyester. More particularly, it relates to a crystallization method that comprises a step of providing a polyester comprising at least one 1,4:3,6-dianhydrohexitol unit, and a step of crystallizing said semi-crystalline polyester, said method being characterized in that the crystallization step is performed at a pressure of at least 600 mbar absolute. The method according to the invention makes it possible to strongly limit, or even eliminate, the phenomenon of polyester expansion during crystallization. Advantageously, the elimination of the expansion phenomenon through pressure conditions implemented according to the invention thus makes it possible to dispense with obtaining very fragile empty spheres that break when agitated and thus cause the formation of undesirable fine particles.

Abstract: The invention relates to a thermoplastic composition comprising: at least one mixture of polyesters (A) including at least one polylactic acid (A1) and at least one aliphatic polyester (A2) or a semi-aliphatic polyester other than polymer (A1); at least one starch (B); at least one organic plasticiser (C) for starch. The composition is characterised in that: the weight percentage of (A1) in relation to the weight of (A1) and (A2), expressed as dry weight, varies between 2 and 70%, advantageously between 10 and 50%, preferably between 18 and 30%; at least 50% of the weight of the polylactic acid (A1) is formed by semi-crystalline polylactic acid; and in that the weight ratio of starch (B)/organic plasticiser (C), expressed as dry weight, varies between 90/10 and 40/60.
