    • 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 of urethane bonds, the number average molar mass, M.sub.n, of the prepolymer is at least 10,000 g/mol, its mass-average molar mass, M.sub.w, is over 20,000 g/mol and its molar mass distribution, expressed as the ratio of M.sub.w /M.sub.n, is over 2, and the prepolymer 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 molded pieces and thermoformed and blow molded packages, bags, sacks and bottles, for coating of sacks, bags and films made of paper or cardboard, and for manufacturing fibers and non-woven fabrics.

    • 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 polyoon-densation 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。 聚酯树脂通过多孔致密反应直接生产,然后与高分子量的聚合物交联。聚酯可以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。
