摘要： The Invention relates to a method for the preservation of natural rubber latex comprising the step of adding to natural latex at least one hydrophobically modified saccharide. The hydrophobically modified saccharide is prefererably a hydrophobically modified fructan, a hydrophobically modified starch hydrolysate, or a mixture thereof. The invention further relates to a natural rubber latex containing a hydrophobically modified saccharide, and to vulcanised natural rubber products containing a hydrophobically modified saccharide.

摘要： A method for the preservation of natural rubber latex is disclosed which comprises adding to natural rubber latex at least one hydrophobically modified saccharide in combination with at least one conventional preservative, preferably ammonia.
The method enables increasing the stability of natural rubber latex by an economically interesting method which does not negatively affect neither subsequent conventional processing of the latex, nor the properties of shaped rubber articles manufactured from the stabilized latex.
Furthermore, preserved rubber latex is disclosed that is stabilized by the method of the invention. Also preserved non-concentrated as well as concentrated rubber latex is disclosed comprising at least one said hydrophobically modified saccharide in combination with at least one conventional preservative, preferably ammonia.摘要翻译： 公开了一种保存天然橡胶胶乳的方法，其包括将至少一种疏水改性的糖与至少一种常规防腐剂（优选氨）一起加入到天然橡胶胶乳中。 该方法能够通过经济上有趣的方法提高天然橡胶胶乳的稳定性，这不会对后续的胶乳的常规加工产生负面影响，也不影响由稳定的胶乳制成的成型橡胶制品的性能。 此外，公开了通过本发明的方法稳定的防腐橡胶胶乳。 还公开了保存的非浓缩以及浓缩橡胶胶乳，其包含至少一种所述疏水改性的糖与至少一种常规防腐剂，优选氨的组合。

摘要： A means for stabilizing a deproteinized natural rubber latex is disclosed, comprising adding a stabilizer selected from the group consisting of (a) an anionic surfactant, (b) an amphoteric surfactant, (c) a nonionic surfactant, (d) a nonionic or amphoteric oligomer or polymer, and (e) an anionic oligomer or polymer. By adding the stabilizer, the mechanical stability of a deproteinized natural rubber latex can be markedly improved.

摘要： The present disclosure provides for a process for manufacturing of dipped latex products without using any animal derived ingredients and dipped latex products produced by said process. The disclosed process successfully over comes drawbacks of drop in product yield (due to coagulum formation) and burst pressures caused by absence-of casein in latex formulation. Therefore, the dipped latex products so produced through the process have final composition similar to that of any other dipped latex products with casein except for absence of casein and having 0.8 phr of Sulphur as against 0.6 phr of Sulphur in routine manufacturing. The products also exhibit physical properties similar to that of any other dipped latex products with casein, such as burst pressure and burst volume.
