    Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of thermoset polymer particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.

  • Publication number: 20140238676
    Abstract: A cement slurry composition is described as having cement, water, and organic polymeric particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propyxlate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry and to reduce or prevent foaming. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set into a solid mass in the zone.

  • Patent number: 8800656
    Abstract: A self-adaptive cement formulation includes cement, water, block copolymer and asphaltite-mineral particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self-healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.

  • Patent number: 8716370
    Abstract: A roof sloping compound for creating an auxiliary slope over a wide variety of roof membranes and substrates. The compound includes a dry mixture of aggregate, cement and a redispersible dry polymer adapted to be mixed with water to define a substantially self-leveling consistency enabling the compound to be readily screeded into place in a desired thickness. The aggregate comprises dolomite or limestone and the redispersible dry polymer can comprise a binder based on a copolymer of ethylene vinyl acetate. In a lightweight embodiment of the compound, the aggregate includes lightweight fillers comprising perlite and low density glass granules and a superplasticizer is added to the dry mixture to reduce water demand.
