WebA novel shale inhibitor was synthesized by free radical copolymerization in aqueous solution, using acrylic acid (AA), acrylamide (AM), maleic anhydride (MA) KH-570 as reaction monomers and potassium persulfate as initiator. The structure of the copolymer was characterized by Fourier transform infrared spectroscopy (FT-IR). Thermogravimetric … Polymerisation inhibitors (US: polymerization inhibitors) are chemical compounds added to monomers to prevent their auto-polymerisation. Unsaturated monomers such as acrylates, vinyl chloride, butadiene and styrene require inhibitors for both processing and safe transport and storage. Many monomers are … See more The term 'inhibitor' is often used in a general sense to describe any compound used to prevent unwanted polymerisation, however these compounds are often divided into 'retarders' and 'true inhibitors'. A true inhibitor has a … See more • Anti-skinning agent - These agents prevent polymerisation in paints and varnishes by binding to, and thus inhibiting, the action of oil drying agents • Tubulin polymerisation inhibitors - chemotherapy drugs that interfere with the tubulin system See more True inhibitors Radical polymerisation of unsaturated monomers is generally propagated by C-radicals. These can … See more Purified monomers stored at ambient temperatures are of less risk of polymerising and as such the most highly reactive inhibitors … See more
WebJul 9, 2024 · The inclusion of (macro)molecules that inhibit unwanted dye adsorption onto fabrics within laundry detergent formulations may be exploited as a highly beneficial, and nondetrimental, mode of dye transfer inhibition.

When the active agent is used as a drug, corrosion inhibitor, or pesticide, it can be released upon a specific stimulus. The efficiency and the sustainability of active agents are determined by the released kinetics.
WebThe polymer chain growth process is known as propagation, and this will continue until termination of the chain is achieved and the reaction comes to an end. This may come about through undesirable side reactions of radical initiators, unwanted auto-polymerization or, more intentionally, by reacting with an inhibitor.
