A device for purifying at least one fluid is provided. The device includes at least a first ion exchange column, an inlet line and an outlet line. The inlet line and the outlet line are associated with a cover part, the inlet line is connected to a first supply line into a first free space between a bottom part and at least one nozzle insert, which is formed as a first bottom nozzle insert, and the nozzle insert has a number of openings for the passage of the fluid. The openings are distributed over at least a partial surface of the nozzle insert, by which the fluid can be introduced into a first volume of the ion exchange column which can be filled with an ion exchange resin.

A multi-layer polymer film comprising at least one middle layer A, the polymeric constituents of which are soluble in aqueous solution, and in each case at least one substantially water-impermeable covering layer B, C arranged above and below the at least one middle layer A, wherein the layers A, B and C independently of each other in each case comprise at least one thermoplastic polymer and at least one of the covering layers B and C comprises at least one polyhydroxyalkanoate is presented and described. Processes for the production of the multi-layer polymer film according to the invention and its use for the production of molded parts, films or bags are furthermore presented and described.

A process is presented and described for the production of moldings, comprising the steps of (a) providing a polymer composition comprising from 1 to 99% by weight of polyhydroxyalkanoate and from 1 to 99% by weight of starch-containing polymer; (b) homogenizing the polymer composition with use of thermal and/or mechanical energy; (c) introducing the polymer composition into a mold; (d) molding the molding in the mold; and (e) removing the molding from the mold. The process described is in particular suitable for the production of hard capsules.

Method for producing moulded parts

A polymer composition is presented and described and includes, based on the total weight of the polymer composition, the following components: a. from 15 to 70% by weight of PLLA, b. from 0.1 to 15% by weight of PDLA, c. from 5 to 40% by weight of polyester, and d. from 5 to 40% by weight of organic or inorganic filler. These polymer compositions can be biodegradable, comprise mainly bio-based carbon, and have an increased heat deflection temperature. These polymer compositions can moreover be used in specific processes in order to produce molded parts, films, or fibers which by virtue of their high heat deflection temperature can also be used as containers for coffee-preparation systems.

Polymer composition containing PLLA and PDLA

The invention relates to a polymer compound which, based on the total weight of the polymer compound, comprises at least the following components: (a) 5 to 50 wgt.-% destructed starch and/or starch derivative, (b) 20 to 70 wgt.-% aliphatic-aromatic copolymer, (c) 10 to 50 wgt.-% polyhydroxyalkanoate and (d) 3 to 25 wgt.-% polyactic acid. Such polymer compounds are characterized by a high ratio of bio-based carbon and exhibit no significant embrittlement or worsening of the mechanical properties profile, despite the presence of increased volumes of polyhydroxyalkanoate, even after storage. The invention further relates to production methods for the polymer compound according to the invention, and use thereof in the production of films, molded parts or fibers.

A method for the production of a polymer material is shown and described, which is characterized by: a) producing a mixture containing at least 1 to 75 wt.-% starch and/or starch derivative, 10 to 85 wt.-% polyester, and 0.01 to 7 wt.-% of a polymer containing an epoxy group; (b) homogenizing the mixture while supplying thermal and/or mechanical energy; (c) setting the water content of the mixture, so that the end product has a water content less than approximately 12 wt.-%, in relation to the total composition of the mixture. The polymer material produced with the method according to the invention is characterized by outstanding mechanical properties.

A dehydratable hygiene article contains a lower layer which is impermeable to aqueous liquids, an upper layer which is permeable to aqueous liquids, a core disposed between the lower and upper layer and absorbs aqueous liquids, and a trigger system containing a superabsorbent material which is capable of absorbing aqueous liquids with the formation of a hydrogel. After the trigger system has been activated, at least some of the aqueous liquid absorbed can be released from the superabsorbent material when it is present as a hydrogel. The hygiene article contains at most 50 wt. % of a further superabsorbent material. Based on the total weight of superabsorbent material and further superabsorbent material, which would be capable, after the trigger system has been activated, of at least partly absorbing, with the formation of hydrogel, the aqueous liquid which is at least partly released.

The aim of the invention is to obtain filter tows or filtering materials for manufacturing filters for smoking products which make it possible to prevent or at least reduce health risks due to the release of the filter components and external contamination of cigarettes by filter components. According to the invention, a filter element is manufactured of starch and/or a mixture of a starch-based polymer and eventually incorporated activated-carbon layers and provided with pores and/or channels. The filter particles eventually adherent to such filtering materials or released during cigarette smoking can be dissolved in a corresponding moisture-containing environment. They do not come into consideration for health-damaging effects.

Biodegradable polymer blends suitable for laminate coatings, wraps and other packaging materials are manufactured from at least one 'hard' biopolymer and at least one 'soft' biopolymer. &#x201c;Hard&#x201d; biopolymers tend to be more brittle and rigid and typically have a glass transition temperature greater than about 10&#xb0; C. &#x201c;Soft&#x201d; biopolymers tend to be more flexible and pliable and typically have a glass transition temperature less than about 0&#xb0; C. While hard and soft polymers each possess certain intrinsic benefits, certain blends of hard and soft polymers have been discovered which possess synergistic properties superior to those of either hard or soft polymers by themselves. Biodegradable polymers include polyesters, polyesteramides, polyesterurethanes, thermoplastic starch, and other natural polymers. The polymer blends may optionally include an inorganic filler. Films and sheets made from the polymer blends may be textured so as to increase the bulk hand feel. Wraps will typically be manufactured to have good &#x201c;dead-fold&#x201d; properties so as to remain in a wrapped position and not spring back to an &#x201c;unwrapped&#x201d; form.
