    摘要： The present invention relates to a dendritic comb-shaped polymer thickening agent and preparation and application thereof; it is a copolymer obtained by copolymerization of monomer (A) and monomer (B). Monomer (A) is one or more water-soluble unsaturated monomers with olefin chain, and monomer (B) is at least one monomer with the following general structure: wherein R1, R2 is selected from H or C1˜C12 alkyl group, respectively; R3, R4, R5 is selected from H or C1˜C8 alkyl group, C1˜C8 alkylaryl group, C1˜C8 alkyl ether or C1˜C8 alkyl ester group, respectively; A′ is selected from COO− or OH. The content of the monomer (A) is 70˜99.99% of the total mass of the monomer (A) and the monomer (B), and the content of monomer (B) is 0.01˜30% of the total mass of the monomer (A) and the monomer (B). The viscosity of the polymer solution with the present polymer is 30% higher than that with common polyacrylamide and it is used in polymer flooding for oil reservoir with permeability lower than 400 mD in oilfields.

    摘要： A process for preparing vinyl aromatic-allylic alcohol copolymers, such as styrene-allyl alcohol (SAA) copolymers, is disclosed. The process is conducted in the presence of a solvent, which enables the preparation of copolymers having both low hydroxyl functionalities and low molecular weights. SAA copolymers produced by the process have an average hydroxyl functionality less than about 4.
