    • The object of the present invention is a biodegradable polymer network and methods to make it. The polymer network consists of a cross-linked polyester resin, which is composed of hydroxy acid units, structural units derived from an unsaturated bifunctional monomer, and structural units derived from a polyol monomer. The polyester resin is produced directly by a polycondensation reaction, after which it is cross-linked to a polymer of high molecular weight. The polyester can be co-polymerised with a co-monomer increasing flexibility, or be blended with a reactive macromonomer, which adds elasticity and crosslinking density. The prepared polymer network can be especially used to coat continuous or singular objects made of fibrous, porous, biomass based or inorganic materials, or as a blending component in these, or used to impregnate these in order to induce water durability, barrier properties, elasticity, coherence or mechanical strength.
    • 本发明的目的是可生物降解的聚合物网络及其制备方法。 聚合物网络由由羟基酸单元组成的交联聚酯树脂,衍生自不饱和双官能单体的结构单元和衍生自多元醇单体的结构单元组成。 聚酯树脂通过缩聚反应直接制备,然后与高分子量的聚合物交联。 可以将聚酯与增加柔性的共聚单体共聚,或与反应性大分子单体共混,这增加了弹性和交联密度。 制备的聚合物网络可以特别用于涂覆由纤维,多孔,生物质基或无机材料制成的连续或单个物体,或作为其中的共混组分,或用于浸渍这些物质,以引起水的耐久性,阻隔性,弹性 ,一致性或机械强度。

    • Polyesters of organic hydroxy acids and their derivatives are, because of their ester linkages prone to hydrolysis, an important group of potentially biodegradable polymers. The mechanical properties of thermoplastic materials based on them have, however, been inferior for many applications, especially when melt processability is required. By the present method which comprises a two-step reaction and the use of a linking monomer it is possible to produce copolyester based polyurethanes from lactic acid and another organic hydroxy acid having a long flexible hydrocarbon chain in its molecules or corresponding lactone, as epsilon -caprolactone. By the proper choice of reaction parameters one can thus get materials which are unexpectedly strong, tough and/or elastic. By melt blending inherently brittle biodegradable polymers with a copolyester based polyurethane according to the invention it has been possible to prepare materials with significantly improved impact strength.
    • 有机羟基酸及其衍生物的聚酯,因为它们的酯键易于水解,是一组重要的潜在可生物降解的聚合物。 然而,基于它们的热塑性材料的机械性能对于许多应用来说是劣质的,特别是当需要熔融加工性时。 通过包括两步反应和使用连接单体的本发明方法,可以从乳酸和其分子中具有长柔性烃链的另一有机羟基酸或相应的内酯生产共聚酯基聚氨酯, 己内酯。 通过适当选择反应参数,可以得到出乎意料的坚固,坚韧和/或弹性的材料。 通过将本发明的易生物降解聚合物与基于共聚酯的聚氨酯熔融共混,可以制备具有显着改善的冲击强度的材料。

    • The invention concerns a novel melt-processible poly(ester urethane) and a process and a prepolymer for the preparation thereof. The poly(ester urethane) contains structural units derived from a polyester and structural units derived from a diisocyanate and, according to the invention, the bonds between the structural units are at least mainly comprised only of urethane bonds, the number average molar mass, Mn, of the polymer is at least 10,000 g/mol, its mass-average molar mass, Mw, is over 20,000 g/mol and its molar mass distribution, expressed as the ratio Mw/Mn, is over 2, and the polymer is essentially free from free isocyanate groups. The poly(ester urethane) is hydrolytically decomposable and it can be used as a biodegradable polymer, e.g., for manufacturing injection moulded pieces and thermoformed and blow moulded packages, bags, sacks and bottles, for coating of sacks, bags and films made of paper or cardboard, and for manufacturing fibres and non-woven fabrics.
