Disclosed herein are process for increasing the molecular weight of guayule natural rubber that is solubilized in an organic solvent solution. The processes utilize shear desolventizing to achieve the increase in molecular weight.

Provided herein are methods for the removal of organic solvents from wet bagasse. The use of the methods result in dried bagasse that contains no more than 1 weight percent organic solvents.

There is provided a regeneration method of blade rubber used for a wiper blade. At least a part of the blade rubber constitutes a contact portion with a wiping target object. The regeneration method includes a step of preparing the blade rubber to be regenerated, and a cutting step of entering a cutting blade into the blade rubber from a side portion of the blade rubber at one end portion A of the blade rubber, and moving the cutting blade relative to the blade rubber toward another end portion B of the blade rubber to remove at least a part of the contact portion, and a storage elastic modulus of the blade rubber at a vibration frequency of 110.sup.3 Hz is 90.0 to 500.0 MPa, and a breaking stress of the blade rubber is 4.2 to 30.0 MPa.

A processing facility (1) comprises a processing screw machine (4) for processing dewatered rubber (7) and styrene acrylonitrile, a dewatering screw machine (2) for dewatering wet rubber (6) and providing the dewatered rubber (7), and a feed device (3) for feeding the dewatered rubber (7) into the processing screw machine (4). Because the dewatering and the processing are mechanically decoupled, simple, flexible and efficient processing can be achieved.
