The high quality high-solids hydroxyl acrylic resins were synthesized by free radical polymerization.The influence of initiators

monomers

solvents and transfer reagents on the structure and properties of the resins were discussed.The results show that the optimal factors

solvent of xylene

functional monomers and transfer reagents with proper contents

should provide the resins with molecular weight 3 000-4 000 and the disperse index less than 2.Solidified with HDI

the resins can form high qualify paints with good appearance and performance.
