A noncovalent soft elastomer includes a binary block copolymer composed of an A block and a B block and a solvent, wherein the B block has a noncovalent-bonding functional group, and the solvent is a nonvolatile liquid which has a property of dissolving the B block but not dissolving the A block and which forms a functional group capable of noncovalent-bonding of the B block.

A preparation method of vinyl ester resin for optimizing heat-release during curing includes: (A) providing a vinyl ester, a solvent and a phase change material to perform mixture; (B) performing a heating process to remove the solvent, so as to obtain a vinyl ester resin containing the phase change material. Thereby, the organic PCM material with high heat absorption and good resin affinity can be used as the temperature control agent of the vinyl ester resin during the curing process for avoiding the defects such as bubbles and cracks being generated in the vinyl ester resin.

The present invention relates to rubber or elastomer compositions as can be used for vehicle tires, and to a method for the production of the rubber or elastomer compositions. The elastic modulus of the compositions can be adapted depending on the temperature and/or the application conditions, and is a cost-effective and easily implemented method for the production of the compositions. The rubber or elastomer compositions contain at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form. The compositions may be made by mixing the at least one rubber and the at least 20 to 150 phr of a phase change material in solid or liquid form, or the at least one rubber is at least brought into contact with the phase change material, and further processing steps can be performed, and a vulcanization can be performed.

It discloses a lignin enhanced wood-plastic composite, belonging to the field of polymer based composites. The wood-plastic composite is composed of one or more of plant fiber, lignin, a recycled thermoplastic plastic, mineral powder and a processing aid, and is processed by a screw granulating extrusion process. Compared with the prior art, the mechanical properties, heat stability and aging resistance of a wood-plastic material are improved by adding lignin into the wood-plastic material according to the present invention.
