  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.

  本发明的目标是一种可生物降解的聚合物网络及其制备方法。该聚合物网络由交联的聚酯树脂组成，该聚酯树脂由羟酸单元、来自不饱和双官能团单体的结构单元和来自多元醇单体的结构单元组成。聚酯树脂通过聚缩酰胺反应直接制备，随后与高分子量的聚合物交联。聚酯可以与共聚单体共聚以增加柔性，或与反应性大分子单体混合，以增加弹性和交联密度。制备的聚合物网络可以用于涂覆由纤维、多孔、生物质基或无机材料制成的连续或单个物体，或作为这些物体的混合组分，或用于浸渍这些物体以诱导耐水性、隔离性、弹性、连贯性或机械强度。

  The invention discloses composition, prepolymer and method to produce a polymer based on biodegradabler or essentially renewable crude materials, which can be crosslinked by free radicals. Composition is based on polyesters that are functionalised with unsaturated monomer units, in a way that unsaturated groups can be located along the polymer main chain as well as at the ends of the prepolymer. In connection to the product production, the prepolymer shall be exposed to free radicals that leads to network formation. The composition of the crosslinked biopolymer can be adjusted from a stiff engineering material to an elastic rubbery material. The new biopolymer can be used in composite materials, dispersions, barrier materials, rubbery materials, and in biomedical applications to mention a few possible application areas.

  The present disclosure is directed degradable polymers. The polymers are solid when maintained under substantially dry conditions at a temperature of up to about 90 degrees C. When contacted with water at a temperature of up to about 90 degrees C., however, the polymers initially remain solid for a period of up to about 6 to about 24 hours, then depolymerize to provide a liquid having a viscosity of from about 1 to about 200,000 centipoise after a period of time from about 8 hours to about 3 days and then further depolymerizes to water-soluble components after a period of time at least about 3 days. Also disclosed are sand screen coatings made with the polymers and hydraulic and acid fracturing methods using the polymers.
