In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats.

  • Patent number: 8822139
    Abstract: A method for providing an ordered polymer layer at a surface of a substrate includes depositing a self-assemblable polymer layer directly onto a primer layer on a substrate to provide an interface between the self-assemblable polymer layer and the primer layer, and treating the self-assemblable polymer layer to provide self-assembly into an ordered polymer layer, such as a block copolymer, having first and second domain types at the interface. The primer layer is adapted to improve its chemical affinity to each domain type at the interface, in response to the presence of the respective domain type in the self-assembled polymer at the interface during the self-assembly of the self-assemblable polymer layer into the ordered polymer layer. This may lead to reduction in defect levels and/or improved persistence length for the ordered polymer layer. The method may be useful for forming resist layers for use in device lithography.

  • Publication number: 20140227520
    Abstract: A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of a synthetic material such as polymer and the synthetic material is functionalized with molecules having a functional group for attracting mineral particles to the surface in a separation process. The synthetic beads can be placed in flotation cell containing a mixture of water, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.
