What is Dimethylaminoethyl Acrylate CAS 2439-35-2?
Dimethyloxyethyl acrylate (DMAEA) is a key monomer for water treatment, biomedicine and smart materials due to its bifunctional reactivity and pH-responsive properties. Its safety needs to be strictly controlled (such as the addition of anti-agglomerating agents and protective equipment), and the design of block copolymers is driving its innovative applications in precision medicine. Future research should focus on:
Deepening of toxicity mechanism: Clarify the impact of chronic exposure on the reproductive system;
Improvement of biocompatibility: Develop low-toxicity copolymer structures (such as PEG modification);
Scaling up of green production: Optimize catalytic processes to reduce BDO dependence.
Functional group characteristics
Dual reaction sites:
Acrylate group: Participates in free radical polymerization (e.g., copolymerization with acrylamide, styrene).
Tertiary amine group (-N(CH₃)₂): Provides pH responsiveness. Under acidic conditions, it is protonated to form a cation, enhancing hydrophilicity and charge interaction.
Self-polymerization tendency: Sensitive to light and heat, requires the addition of a stabilizer (such as MEHQ, with a content of 1000-2000 ppm).
Polymerization behavior
Homopolymer/Copolymer: Can synthesize linear or block polymers, precisely controlling molecular weight and structure through RAFT polymerization.
Intelligent responsiveness:
pH response: Solubility changes after protonation (pKa ≈ 8.2), suitable for controlled-release carriers.
Temperature synergy: When copolymerized with NIPAM blocks, it exhibits dual-response self-assembly (such as micelle formation) under temperature/pH conditions.
Dimethylaminoethyl Acrylate CAS 2439-35-2 Use
1. Industrial Chemical Synthesis
Water treatment flocculants: Form cationic poly electrolytes through copolymerization with acrylamide, effectively adsorbing suspended particles.
Oilfield chemicals: As drilling fluid additives, they improve clay stability and rheological properties.
Anti-static coatings: The copolymer is used in electronic packaging materials to eliminate static charge accumulation.
2. Biomedical Materials
Drug Delivery Systems:
Block copolymers (such as PNIPAM-b-PDEAEAM) release drugs in the tumor microenvironment (pH 6.5).
Cationic nucleic acid (DNA/RNA) complexes are used for gene vector design.
Antibacterial agents: Protonated polymers disrupt bacterial membranes (such as medical device coatings).
3. Functional Polymers
Smart-responsive materials: Respond to environmental changes (such as temperature/pH) in sensors and self-repairing coatings.
Papermaking additives: Enhance fiber bonding strength and improve paper strength.
