Abstract

The invention discloses a preparation method of a rosinyl acrylamide polymer. The preparation method comprises the following steps in sequence: (1) enabling dehydroabietylamine and acryloyl chloride to react for 2 to 5h at the temperature of 5 to 15 DEG C, so as to prepare a rosinyl acrylamide monomer; (2) enabling the rosinyl acrylamide monomer obtained in the step (1) to react continuously for 0.5 to 4h at the temperature of 60 to 75 DEG C under the condition that an initiator exists after sediments occur during the reaction, so as to prepare the rosinyl acrylamide polymer. According to the rosinyl acrylamide polymer and the preparation method thereof, provided by the invention, natural biomass resources are taken as raw materials to synthesize the rosinyl acrylamide polymer, the synthetic steps are simple, the heat resistance of the polymer is excellent, the defects that an acrylamide polymer is in sufficient in heat resistance and salt tolerance are overcome, and meanwhile, the technical problem of environment protection and safety is also considered.

Description

technical field [0001] The invention relates to a preparation method of a rosin-based acrylamide polymer. Background technique [0002] Polyacrylamide (PAM) is a polymer with different structures and properties obtained from acrylamide (AM) monomer through homopolymerization or copolymerization with other vinyl monomers. Developed countries in the world have successively developed high-molecular-weight, high-performance acrylamide polymers and their copolymers and derivatives, which are widely used in petroleum exploration, papermaking, water treatment, textiles, medicine, agriculture and other industries. say. [0003] Since my country is a country with shortage of oil resources, water resources and forest resources, the application of PAM in oil extraction, water treatment and papermaking industries has important strategic significance. At present, the largest consumption of polyacrylamide in my country is oil recovery, followed by water treatment and papermaking. In 20...
