Abstract: The invention relates to a process for obtaining natural rubber from plant material containing at least the step of milling the plant material with at least one ball mill comprising milling media. The invention further relates to the natural rubber obtained by this process and to the use of at least one ball mill comprising milling media for milling plant material when obtaining natural rubber from plant material. In the process, the ball mill has a nonmetallic lining and/or the milling media have at least a nonmetallic surface.

Abstract: The present invention relates to a process for obtaining aging-resistant natural rubber, to a rubber composition comprising the thus-obtained natural rubber and to the use of this composition for producing consumer goods.

Abstract: The present invention relates to a method for separating poly-isoprene and/or other apolar valuable substances from vegetable feedstock, with a first pretreatment (100) of the vegetable feedstock; a percussive, cutting and/or rubbing mechanical processing (102) of the vegetable feedstock after the pre-treatment in a wet phase, during which the polyisoprene and/or other apolar valuable substances contained in the processed raw plant materials are extracted from the vegetable feedstock; and after the mechanical processing (102), a separation (104) of the polyisoprene and/or the other apolar valuable substances from the wet phase. The invention proposes that, before or during the mechanical processing (102) in the wet phase, an adsorber material (106) be added to the ground product mixture to create a method which makes it possible to obtain polyisoprene and other apolar valuable substances from plants having a low rubber content in a technically simpler manner.

Abstract: The present invention relates to a grinding media mill (2) for obtaining polyisoprene and/or other apolar materials from raw plant materials, having a drum (4) which is peripherally closed and has a milling chamber (10) that is peripherally closed and located in the interior of the drum (4). The aim of the invention is to create a grinding media mill that enables careful processing of the raw plant materials, on the one hand, but is also variable in processing intensity and throughput time, on the other hand.

Abstract: The invention provides a method of reducing or eliminating the content of triterpenes and/or triterpenoids of latex or rubber from a laticiferous plant or part thereof, comprising genetically modifying the laticiferous plant or part thereof, such that the activity of at least one oxidosqualene cyclase is reduced or eliminated, compared to the respective wild-type or untreated laticiferous plant or part thereof. The invention further provides a laticiferous plant or part thereof being genetically modified such that the activity of at least one oxidosqualene cyclase is reduced or eliminated, compared to the respective wild-type or untreated laticiferous plant or part thereof, and an RNAi being specifically directed against a mRNA transcript of at least one oxidosqualene cyclase, for use in a method of reducing or eliminating the content of triterpenes and/or triterpenoids of latex or rubber from a laticiferous plant or part thereof.

Abstract: The present invention relates to a composition comprising (i) a crosslinkable synthetic cis-1,4-polydiene having a cis content of at least 95% and a functional group in the terminal position, and (ii) an amphiphilic compound.

Abstract: The present invention relates to a method of increasing the yield of at least one of oxidosqualene, triterpenes and/or triterpenoids in a specifically engineered host cell and a respective host cell as well as to the use of said host cell for manufacturing the at least one of oxidosqualene, triterpenes and/or triterpenoids.
