Description
4-Hydroxybutyl Acryrate Glycidyl Ether with a glycidylether group at the end of a longer alkyl chain, gives excellent scratch resistance due to its high crosslinking ratio and unique flexibility.This copolymer has good acid rain resistance.It is used in Paint and coating materials,UV/EB curable composition.
Chemical Properties
4HBAGE has a glycidylether functional group and a double bond group in the molecule.Various vinyl monomers can be copolymerized with 4HBAGE.The co-polymerized polymer with 4HBAGE achieves a higher crosslinking ratio with curing agents.This is because the glycidylether is further away from the copolymer backbone chain.This copolymer has good acid rain resistance.
Application
Paint and coating materials (excellent scratch resistance, mechanical properties, and chemical properties)
Powder coatings
UV/EB curable composition.
Epoxy acrylate
Adhesives
Synthesis
The flask was charged with 144 g of 4-hydroxybutyl acrylate and 0.7 g of boron trifluoride ether complex as a catalyst, heated to 55 ° C., and then 92.5 g of epichlorohydrin was added dropwise over 2 hours with stirring. After completion of the dropwise addition, analysis by gas chromatography revealed that the conversion rate of 4-hydroxybutyl acrylate was about 70%, and most of it was converted to a chloroether form.
