Embodiment 1

[0047] Embodiment 1: Initiator azobisisobutyronitrile AIBN is used for bulk polymerization to prepare polyacetoacetoxyethyl methacrylate (PAAEMA)

[0048] 0.5% AIBN was dissolved in the monomer acetoacetoxyethyl methacrylate (AAEMA), and added to a dry three-necked round-bottom flask with a stirrer and a thermometer. Under gentle stirring, blow nitrogen for 10 minutes and heat to 60°C. The monomer is pre-polymerized into a liquid with a higher viscosity, and it is poured into the mold. After sufficient degassing, the prepolymer was allowed to continue polymerizing at 50°C. Finally, at 105°C, heating was continued for 2 hours to complete the polymerization reaction.

Embodiment 2

[0049] Embodiment 2: Initiator AIBN is used for bulk polymerization to prepare polyethylene ethyl acryloyl acetate

[0050] 0.5% AIBN was dissolved in the monomer ethyl allyl acetate (EAA), and added to a dry three-necked round-bottom flask with a stirrer and a thermometer. Under gentle stirring, blow nitrogen for 10 minutes and heat to 60°C. The monomer is pre-polymerized into a liquid with a higher viscosity, and it is poured into the mold. After sufficient degassing, the prepolymer was allowed to continue polymerizing at 50°C. Finally, at 105°C, heating was continued for 2 hours to complete the polymerization reaction.

Embodiment 3

[0051] Embodiment 3: Initiator AIBN is used for bulk polymerization to prepare polyacryloyl ethyl ketone

[0052] 0.5% AIBN was dissolved in monomer propionylacetone (AA), and added into a dry three-necked round-bottomed flask equipped with a stirrer and a thermometer. Under gentle stirring, blow nitrogen for 10 minutes and heat to 60°C. The monomer is pre-polymerized into a liquid with a higher viscosity, and it is poured into the mold. After sufficient degassing, the prepolymer was allowed to continue polymerizing at 50°C. Finally, at 105°C, heating was continued for 2 hours to complete the polymerization reaction.

Abstract

The invention discloses a novel polymer fluorescent material which takes a Beta-dione aggregative structure as a fluorescent luminophor and can be prepared through emulsion polymerization, solution polymerization and body polymerization. The luminous material can be a polymer emulsion or aggregative state solid and film. The invention is characterized in that a polymer is successfully dispersed in a water medium by adopting a novel emulsion polymerization technology to form nano-grade emulsion particles and the polymer forms a Beta-dione aggregative luminous fluorescent structure in a nano limit space. The Beta-dione aggregative luminous fluorescent structure acts with substances of an amine group to form a fluorescent composite so that the polymer emulsion has remarkably enhanced fluorescence and emits strong macroscopic fluorescence under UV light. When the polymer forms an aggregative state solid or film, the Beta-dione aggregative structure emits fluorescence which can be further enhanced by the substance containing the amine group. The material has no toxicity or nocuity and environment protection.

Description

technical field [0001] The invention relates to a novel fluorescent polymer with a β-diketone aggregation structure as a fluorophore, and a synthesis method of the polymer. The invention also relates to the technology of applying the polymer to environment-friendly paints and cosmetics, as a fluorescent tracer of compounds with amine groups and as a fluorescent marker of living substances. Background technique [0002] Fluorescent polymers have attracted widespread interest because of their material diversity and material flexibility. Various high-tech applications have been continuously explored, including application to special inks, paints, and coatings; fluorescent tracers and fluorescent markers for living matter, as well as laser materials, solar concentrating materials, and light scintillation materials. Most fluorescent polymers are polymerized by vinyl-containing low-molecular-weight fluorophore substances. These polymerizable monomers are derivatives of polyaromat...
