FOAMABLE RESIN COMPOSITION
The present disclosure provides a foamable resin composition. The foamable resin composition includes a polyurethane (meth) acrylate oligomer, a photoinitiator, a heat-expandable microcapsule, and a photopolymerizable monomer.
HOLLOW PARTICLE-CONTAINING ELASTOMER COMPOSITION AND METHOD FOR PRODUCTION THEREOF
Provided are a hollow particle-containing elastomer composition in which high dimensional stability is retained in the molding step, and properties/functions of the hollow particles are less likely to deteriorate; and a method for production thereof in which the hollow particles are less likely to collapse in the kneading step. The provided elastomer composition comprises a base material and hollow particles comprising a specific resin, and has a storage elastic modulus G at 60 C. of 2.5 MPa or less; and also has a residual void ratio of 80% or more which is measured by a predetermined method. In the provided method, a raw material mixture is kneaded in both steps of preliminarily kneading and finishing kneading at a temperature at which the storage elastic modulus G becomes 2.5 MPa or less.
METHOD FOR PRODUCING POLYIMIDE HOLLOW PARTICLES AND POLYIMIDE HOLLOW PARTICLES
A method is capable of producing polyimide hollow particles does not require the use of template particles, does not require conditions of a high temperature and a high pressure, and is capable of producing polyimide hollow particles having excellent heat resistance. A polyimide hollow particle with excellent heat resistance which is obtained by such a production method is provided. A production method for polyimide hollow particles each having a shell portion and a hollow portion surrounded by the shell portion, including: preparing an inner oil phase containing polyamic acid fine particles and a solvent; preparing an outer oil phase containing a hydrocarbon-based solvent and at least one selected from the group consisting of a compound having a siloxane bond and a silicon dioxide; and carrying out a chemical imidization reaction in an emulsion prepared from the inner oil phase and the outer oil phase.
BIO-DEGRADABLE ARTIFICIAL LEATHER COMPOSITION
Present invention is related to a bio-degradable PVC artificial leather composition having: PVC powder 100 phr, a plasticizer 4060 phr and a catalyst 0.54 phr. The bio-degradable material has degradation rate over 90% under anaerobic environment. The combination of plasticizer and catalyst give the present invention the ability of degrading. Because there is no additional bio material involved, the physical property and mechanical property of the present invention can be remained. Since the products made by the present invention only can be degraded under anaerobic environment, the products can maintain in good condition or qualities under normal circumstances with the existing of oxygen.
MICROENCAPSULATION OF RUBBER- AND POLYMER-MODIFIED BITUMEN FOR STORAGE AND TRANSPORTATION
The subject invention pertains to compositions and methods of encapsulating bitumen for storage and transportation. More specifically, the capsule surrounding bitumen can contain electrolyte layers, bound through electrostatic interactions, on the surface of bitumen.
Articles of manufacture with polyurea capsules cross-linked with chitosan
Novel articles of manufacture are described based on a combination of an adjunct material and microcapsules made by an improved process. The improved microcapsules are chitosan urea and encapsulate a benefit agent. The process comprises combining an adjunct material formed of microcapsules formed by a water phase comprising hydrolyzing chitosan in an acidic medium at a pH of 6.5 or less for an extended period and combining with a polyisocyanate. The reaction product of the hydrolyzed chitosan and polyisocyanate yields a microcapsule having improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.
Fabrication of aquaporin-based biomimetic membrane
Methods of fabricating a membrane comprising proteoliposomes having protein water channels are provided herein. The method may include providing a porous substrate, depositing a solution containing proteoliposomes on the porous substrate, and then contacting the porous substrate with an aqueous monomer solution and an organic monomer solution to form a selective layer on the porous substrate embedding the proteoliposomes. The method may include depositing the aqueous monomer solution, then the solution containing the proteoliposomes, then the organic monomer solution, to form the selective layer. The present disclosure also describes the membrane and a system operable to accommodate both methods.
