The method includes a water soluble polymer, a breaker system containing at least one aliphatic azo-compound, mixing the viscosified treatment fluid and the breaker composition and allowing the viscosified treatment fluid and the breaker composition to interact whereby the viscosity of the viscosified treatment is reduced. The application of the process in the production of oil and gas and to the treatment fluids is also discussed.

  • Patent number: 10934480
    Abstract: A process for producing a photochromic eyewear lens. In one embodiment at least a layer of modified photochromic poly(urea-urethane) is formed by combining photochromic material and the reaction product of a polyurethane pre-polymer and a mixture of diethyltoluene diamine and one or more polyols, plus catalyst. The mixture comprises both NH2 and OH reactive groups, with at least 0.04 equivalent weights of OH reactive species available for reaction with each 1.0 equivalent weight of excess NCO reactive species available in the pre-polymer. The lens comprising the modified photochromic poly(urea-urethane) can exhibit faster fade-back rates and better photochromic performance than lenses with non-modified poly(urea-urethane).

  • Patent number: 10934488
    Abstract: A polymerizable compound-containing liquid crystal composition of the present invention relates to a liquid crystal composition containing a polymerizable compound represented by general formula (I) and a compound represented by general formula (II) and can be used for a liquid crystal display device imparted with liquid crystal aligning ability by polymerization. The polymerizable liquid crystal composition is required to cause no precipitation in a wide temperature range and have a low viscosity corresponding to fast switching, and a liquid crystal display device using the composition is required to have more stable alignment after polymerization and to cause no defect in display characteristics. In the present invention, the problems can be solved using a specified compound.
