A polymeric composition, a process for producing the composition, and a process for using the composition in, for example, hydrocyanation or isomerization are disclosed. The composition comprises repeat units derived from (1) a carbonyl compound, a monomer, and phosphorochloridite; (2) phosphorus trichloride, a polyhydric alcohol, and an aromatic diol; or (3) combinations of (1) and (2) in which the nonomer can be a polyhydric alcohol, an amine, combinations thereof. The composition can further comprise a Group VIII metal and optionally a Lewis acid. The composition can be produced by (1) contacting a carbonyl compound with the monomer to produce an intermediate and contacting the intermediate with phosphorochloridite; (2) contacting phosphorus trichloride with a second polyhydric alcohol under a condition sufficient to produce a phosphorus-containing polymer and contacting the phosphorus-containing polymer with an aromatic diol; or (3) contacting an N, N-dialkyl dichlorophosphoramidite with a second polyhydric alcohol to produce a polymer phosphoramidite, contacting the polymer phosphoramidite with an acid such as HC1 to produce the phosphorus-containing polymer, which is then contacted with an aromatic diol. The composition can be used as catalyst, for example, for converting an unsaturated organic compound to a nitrile and isomerizing a nitrile.

The invention discloses a functionalized temperature-sensitive polymer, a preparation method of same, and an application of same in (PTM) protein detection. The structure formula of the functionalizedtemperature-sensitive polymer is represented as the formula I, wherein R is CH2, r is 0 or 1, m is any natural number from 20 to 750, n is any natural number from 110-1120, and the structure in the specification is horse radish peroxidase unit. The functionalized temperature-sensitive polymer is a linear polymer, which is produced through a free radical polymerization reaction and has a large number of modificable loci. After functional modification, the temperature-sensitive polymer having a plurality of HRP and a large number of triphenyl phosphine groups can be produced. Compared with an antibody strategy in which only single HRP is carried in the prior art, increasing of numbers of the HRP and the triphenyl phosphine groups can effectively increase the combination capability between the polymer and azide-labeled target proteins and signal amplification effect of chemical-luminescence.

The application discloses a composite oil displacement agent for enhancing oil recovery and its preparation method and application, belonging to the technical field of carbon dioxide displacement. The composite oil displacement agent is obtained after mixing supercritical carbon dioxide and a surfactant with a weight ratio of (100‑1000): 1; wherein, the preparation method of the surfactant comprises the following steps: in formic acid, the first The monomer reacts with formaldehyde to obtain the first reactant; the second monomer reacts with the acid chloride to obtain the second reactant; under the initiator, the first reactant and the second reactant are polymerized to obtain the surface active agent; wherein the first monomer is selected from 3-phenyl-4-pentene-1-amine, 4-pentene-1-amine, 4-methyl-pentene-1-amine and 2-amino At least one of 4-pentenoic acid; the second monomer is at least one of 1-butene, 1-pentene, 1-hexene and cyclopentene.
