Scratch resistant polymer composition, in particular for the manufacturing of rigid, scratch resistant and dimensionally stable building bricks, comprising: a) a bio-based HDPE granulate, produced from ethanol or ethylene obtained from biomass; b) an amorphous polymer and/or (semi)crystalline polymer; c) optionally a mineral filler and optionally a colouring pigment; Furthermore, a method for manufacturing an injection moulding article from the scratch resistant polymer composition is disclosed.

Historically, bitumen from oil sands has been carried over land using trucks, pipelines, or by rail, and over water using tankers. Each mode of transportation faces economic or technical challenges of its own. Here there is provided a method for transporting bitumen, comprising: receiving in a dry bulk shipping container a load of discrete pellets with bitumen entrapped into the pellets, wherein the pellets have non-stick outer surfaces configured to prevent the bitumen from sticking to walls of the container when the pellets are carried in the container; and transporting the dry bulk shipping container containing the pellets over a distance. Alternatively or additionally, the pellets may have non-stick outer surfaces configured to prevent the load from caking when the pellets are carried in the container such that the load of bitumen pellets is substantially free-flowing when the transporting is completed.

Scavenging compounds and compositions useful in reducing sulfide emissions from asphalt, such as polymer-treated asphalt, are disclosed. The scavenger compositions may include sulfide-scavenging agents. The scavenger compositions also include a metal-containing compound and optionally a solvent. Any of the compositions, sulfide-scavenging agents and metal-containing compounds may be anhydrous. Methods of using the compositions to reduce hydrogen sulfide emissions from asphalt are also disclosed.

A solid bitumen pellet, including a mixture of bitumen and an additive, where the additive operates to increase the viscosity of the mixture. Optionally, the pellet includes a protective shell.

The invention relates to the use, as fluxing agent for bitumen compositions, of at least one compound having the formula (I)

R.sup.1C(O)OR.sup.2 (I) where: each of R.sup.1 and R.sup.2, which may be identical or different, is a linear or branched hydrocarbon chain which does not carry an unsaturated covalent bond, optionally interrupted by one or more oxygen atoms, and optionally carrying one or more hydroxyl functions.

Compositions comprising renewable source derived polymer oil polymerization macroinitiators and multiblock polymer compositions derived therefrom by atom transfer radical polymerization are disclosed. Hard, glossy multiblock copolymers, thermoset multiblock copolymers, thermoplastic block copolymer elastomers, and methods of making and using these types of materials are disclosed.

The present disclosure is related to a family of oil-based dispersions of organic and inorganic metal compounds for use as a hydrogen sulfide scavenger in asphalt, and the preparation thereof. These dispersions comprise organic and inorganic metal compounds, organic solvents, an organoclay suspension agent, an emulsifier and optionally a polymeric stabilizer. The organic and inorganic metal compounds are in the form of micron-sized particles. Copper-based dispersions are particularly effective at reducing the hydrogen sulfide emission of asphalt in the presence of polyphosphoric acid.

Carbon fiber composite additives, media incorporating the carbon fiber composites, and related methods are provided herein. In some aspects, a composition includes at least one medium; and a carbon fiber composite incorporated with the at least one medium, the carbon fiber composite including one or more carbon fibers with an epoxy resin matrix applied thereto to produce a composition having improved characteristics and filtration performance.
