10,301,574 B2 (Marc Johan Declercq, Hans-Jurgen Kohle, Pieter Jan Maria Saveyn) for a fabric enhancer comprising from a fabric softening active of formula that contains either hydrogen, a short chain C1-C6 alkyl, C1-C3 hydroxyalkyl group, a poly(C2-3 alkoxy), or benzyl; a hydrocarbyl group or substituted hydrocarbyl group comprising about 11 to about 21 carbon atoms; and a fabric enhancer compatible anion.
Based on this concept, a new family of alkoxy acrylate based terpolymers has been developed having lower volume swell and [T.sub.g] than the corresponding copolymers.
Most commonly involved free radicals are superoxide, hydroxyl, alkoxy, peroxy, and NO.
The effect of ROS on organic compounds is the formation of an alkoxy radical R[O.sup.*], a peroxy radical RO[O.sup.*], and a semiquinone radical and anionic radical H-[Ch.sup.*] and [Ch.sup.*-].
Phenolic compounds act as antioxidants for the plant because of their ability (1) to donate electrons or hydrogen atoms to ROS, (2) to bind transition of metal ions, thus preventing Fenton reactions, (3) to degrade ROS directly and inhibit lipid peroxidation by trapping lipid alkoxy radical (RO*), (4) to modify the lipid composition thus lowering membrane fluidity and causing a decreased diffusion of free radicals and limit the peroxidation reaction (Sharma et al., 2012).
The BTU compounds having terminal alkoxy groups at the both ends of the molecule show interesting mesogenic behavior, displaying nematic, smectic A, and smectic C phases, depending on the position and length of the alkyl chains [40].
In the presence of water, the alkoxy group of silane coupling agent is hydrolyzed to silanol (-Si-OH), which is the active species in bonding to glass filler or fiber [2, 21-24].
One class of "polysiloxane hybrid" coatings combine epoxy and silicone resins, along with an organofunctional alkoxy silane to "bridge" the two polymer systems.
The first volume covers science of the environmental chamber, the role of water in organic aerosol multiphase chemistry: focus on partitioning and reactivity, a critical review of atmospheric chemistry of alkoxy radicals, the role of nitric acid surface photolysis on the tropospheric cycling of reactive nitrogen species, the atmospheric chemistry of halogenated organic compounds, atmospheric reaction rate constants and kinetic isotope effects computed using the HEAT protocol and semi-classical transition state theory, and recent advances in the chemistry of OH and HO2 radicals in the atmosphere; field and laboratory measurements.
The most important silicon-based water repellent agents are those made of silanes and siloxanes which are polymers containing three alkoxy groups, denoted OR', linked to a silicon atom, with each silicon atom carrying an organic alkyl group, denoted R.
