[EN] A phosphazene-based polymer hydrogel with a chemical cross-linkings formed by radiating ultraviolet (UV) and/or mixing with cross-linking agent and/or enzyme, a method of preparing the same, and a hydrogel forming a chemical cross-linking by radiating ultraviolet and/or mixing with a cross-linking agent and/or an enzyme; where the hydrigel shows a sol-gel behavior and has an excellent solidity by containing the phosphazene-based polymer that is capable of cross-linking at a certain concentration, are provided. [FR] L'invention porte sur un hydrogel polymère à base de phosphazène présentant une réticulation chimique formée par irradiation par un rayonnement ultraviolet (UV) et/ou par mélange avec un agent de réticulation et/ou une enzyme, sur un procédé de préparation de cet hydrogel, et sur un hydrogel formant une réticulation chimique par irradiation par un rayonnement ultraviolet et/ou un mélange avec un agent de réticulation et/ou une enzyme. L'hydrogel manifeste un comportement sol-gel et possède une excellente solidité par le fait qu'il contient le polymère à base de phosphazène qui est apte à la réticulation à une certaine concentration.

The present invention relates to an improved modified polyamide having increased molecular weight and substantially the same or marginally increased viscosity versus shear weight as the unmodified polyamide. A method for modifying polyamides to provide these improved properties also is disclosed wherein a polyamide having an initial molecular weight is contacted with at least one organic peroxide, at least one coagent and/or one free-radical trap to form an improved polyamide having an increased molecular weight and substantially the same viscosity versus shear rate. The present disclosure also relates to polyamide compositions comprising organic peroxides and articles made from the modified polyamide.
