This invention relates to a method for producing functionalised telechelic oligomers, comprising two steps. The first step relates to bringing a raw material comprising at least one high-molecular-weight polymer comprising at least two unsaturations, into contact with a solution comprising at least one metathesis catalyst and at least one functionalising agent. The second step relates to the separation of the functionalised telechelic oligomers produced by the metathesis reaction in ionic liquid medium of the first step.

A thin organic solvent resistant glove is disclosed including: a first polymeric layer in a shape of a glove including at least one of a blend of a polyisobutylene material and a nitrile-butadiene material, or a nitrile-butadiene material; a second polymeric layer in a shape of a glove including at least one of a polyisobutylene material or a blend of a polyisobutylene material and a nitrile-butadiene material, disposed on the first polymeric layer, and a third polymeric layer in a shape of a glove including a nitrile-butadiene material or an acrylic polymer material disposed on the second polymeric layer.

Objects are to provide: a fusion protein capable of binding to lipid droplets while having an enzymatic activity to synthesize a hydrophobic compound; a method for producing a substance including accumulating a hydrophobic compound in lipid droplets using the fusion protein; a vector which can enhance production of a hydrophobic compound when it is introduced into cells using genetic recombination techniques; and a transgenic cell into which the vector or a gene coding for the fusion protein has been introduced. The disclosure relates to a fusion protein having an amino acid sequence (first amino acid sequence) capable of binding to lipid droplets, and an amino acid sequence (second amino acid sequence) having an enzymatic activity to synthesize a hydrophobic compound, the first and second amino acid sequences being fused via a linker sequence (third amino acid sequence) while maintaining the enzymatic activity of the second amino acid sequence.

Crumb rubber obtained from recycled tires is subjected to a process involving phase reticulation induced sulfidic metathesis. The process utilizes a reactive component that interferes with sulfur bonds, assisted by exposure to a pulsed magnetic field. The resulting rubber, subjected to interlinked substitution, exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, or other polymeric materials, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

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.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
