A process can be used for production of trans-polyoctenamer-graphene composite material having a high filler content, from a trans-polyoctenamer and graphene material. The highly filled trans-polyoctenamer-graphene composite material is useful, for example, in the automotive sector, in heat exchangers, in housings, encapsulations, plain bearings, in 3-D printing heads for heat removal, injection moulded parts, electronics applications, hose systems, membranes, fuel cells, cable systems, indoor and sports apparel, EM protection, and orthopaedics.

Provided is a polymerizable composition comprising a norbornene-based monomer, rare earth element-containing particles having a number-based modal size of 0.05 ?m or more and less than 1.5 ?m, and a metathesis polymerization catalyst.

The present invention provides a method for synthesizing a bifunctional pure organic photocatalytic material with the capabilities of fast adsorption and efficient degradation. By means of reasonably introducing a perylene imide group into an amphiphilic block copolymer, a micelle for treating contaminants in water is formed by self-assembly. The present invention features the advantages in that the micelle formed by self-assembly of the perylene-based amphiphilic block polymer is uniform in size, exhibits ultra-high adsorption capacity on bisphenol A, and can rapidly reach a stable adsorption equilibrium at various concentrations or temperatures. The micelle also demonstrates, in a mixed phenol solution, significant recognition selectivity and good affinity for bisphenol A. In addition, the micelle has rapid degradation efficiency on bisphenol A. The present invention provides a new design concept for the advanced treatment of wastewater by using a metal-free organic material.
