- Process for obtaining biodegradable polyestere- teramide The present specification refers, as its title indicates, to a process for obtaining biodegradable polyestere- teramide, comprising an esterification and / or transesterification and amidation reaction step, a prepolycondensation step, a step of polycondensation, an optional extraction step, a drying step and a final extrusion step with additives.
- the invention pertains to the field of industrial production processes of biodegradable polyestereteramide, abbreviated PEEA, based on aliphatic or aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds, polyetheriamines and other monomers or additives.
- PEEA biodegradable polyestereteramide
- biodegradable polyestere-aramid is known, also abbreviated PEEA, for use in the manufacture of films and molded products, for example for applications of protection of food products, and films for agriculture.
- This biodegradable polyesteretearam contains a compound with at least three groups capable of reacting with one or more types of the active groups present in the reaction mass, ie, compounds containing ether groups in their structure have active groups capable of reacting in the mass of reaction forming amide groups.
- biodegradable refers to the fact that polyestereramide decomposes outdoors in a reasonable time interval, generally by hydrolytic and / or oxidative degradation, enzymatically, or by the influence of microorganisms, such as bacteria, yeasts, fungi and algae.
- the polyestereteramide shows a degree of biodegradability of at least 90% under the conditions specified in DIN EN13432.
- ASTM D5338 and ASTM D6400 There are other methods to determine biodegradability such as ASTM D5338 and ASTM D6400.
- This patent EP2628761 "Biodegradable Polyestereteramide” also describes a process of obtaining 5 stages consisting of:
- Esterification / amidation 1 Stage with temperature adjustment to eliminate low boiling byproducts. Temperature column 65 e C.
- Esterification / amidation 2 Stage with temperature adjustment to eliminate byproducts of higher boiling point. Temperature column 100 e C.
- Chain extender is added to increase the molecular weight. Added on the polymer still melted from the polycondensation. In the reactor of stage 4, through a mixer or in a subsequent processing. Extrusion, injection or physical mixture. In summary, this process consists of two different stages of esterification / amidation, a prepolicondensation, a polycondensation and an addition of chain extenders.
- the present invention relates to a process for obtaining biodegradable polyestere-aramid, different from the known one, and comprising several sequential stages:
- an optional extraction step is introduced, which improves the color in case the color of the product turns orange, without affecting the viscosity or molecular weight
- a drying step is introduced, where the final polymer is conditioned with lower levels of humidity and tetrahydrofuran, making a polymer more suitable for further processing and for contact with food.
- the product obtained after the fifth phase, drying, is temporarily stored.
- additives can be added to improve the polymer and be useful for the final application, such as pigments, dyes, stabilizers, antioxidants, natural preservatives, nucleants, lubricants, reinforcers or fillers, protectors of hydrolytic degradation, thermal or UV radiation, antiblockings, antistatic, thermoplastic starch, PLA, other biodegradable or biobased polymers, compounds that favor foaming, impact modifiers, flame retardants, antifoaming agents and chain extenders.
- additives such as pigments, dyes, stabilizers, antioxidants, natural preservatives, nucleants, lubricants, reinforcers or fillers, protectors of hydrolytic degradation, thermal or UV radiation, antiblockings, antistatic, thermoplastic starch, PLA, other biodegradable or biobased polymers, compounds that favor foaming, impact modifiers, flame retardants, antifoaming agents and chain extenders.

- An important advantage of the production process described here compared to the content of Patent EP2628761 is that it allows the final polymer to be obtained throughout the desired viscosity range and that the final polymer is obtained with low levels of tetrahydrofuran (THF) by incorporating a step of drying and optionally an extraction step, which also reduces the THF content.
- THF tetrahydrofuran
- Another advantage is that said polymer has an improved color compared to the polymer coming from other processes, with improved color meaning that the usual orange hue in the polymer obtained by other processes (color a * > 5, b * : 0-25 expressed in coordinates of the CIELAB color space) decreases or even disappears.
- the final polymer obtained with our invention renders a color in beige tones (color a * ⁇ 5, b * : 0-15 expressed in coordinates of the CIELAB color space), more commercially appreciated in the market.
