It employs a ferrous/hydroperoxide redox initiator system that greatly enhances the molecular weight of the polymer formed. These high molecular weight acrylamide polymers offer outstanding advantages in enhanced oil recovery as injection water viscosifiers.doi:US4617359...
It as been proposed that the physiological function of ceruloplasmin involves the oxidation of ferrous iron and its incorporation into apotransferrin (1). There are several reports demonstrating that ceruloplasmin is made up of multiple chains (2-3-4-5-6-7). Ryden (8) has questioned the ...
RECENTLY, Evans and co-workershave examined the polymerization of methyl methacrylate in aqueous solution, when the initiation of polymerization was by hydrogen peroxide in the presence of ferrous ions. The suggested reaction scheme was as follows: Algebraic expressions were derived giving the rate of...
2. The role of cationic polyacrylamide in oilfield development is to adjust the rheology of injected water, increase the viscosity of driving fluid,improve oil recovery. PackagingAnd Storage: 1.The CPAM solid ispacked in polypropylene woven bags, lined with ...

Ammonium ferrous sulfate was used to prepare the standard solutions, and molar extinction coefficient constant at 562 nm was 28,000 M−1 cm−1. The reducing reagent consists of 48 μL of A [ascorbic acid (4 mM), H2SO4 (0.1 M)] and 2 μL of B [PMS (10 mM...
(processing of the signals by the node), network topology (structure and connections between the nodes), and learning rules (how the weight of the molecular parameters are initialized and adjusted using an algorithm). The nodes in an ANN are usually arranged in three layers: the input, hidden...
1. Field of the Invention This invention relates to the restoration of aqueous solutions of polymers used as quenching baths. Quenching baths are used in the heat treatment and tempering of steels and other ferrous alloys. 2. Prior Art
A lubricant composition comprises an ethylene/α-olefin interpolymer having a number average molecular weight of less than 10,000 g/mol as a base oil and at least one oil additive. T
