Abstract:
A population of polymeric microbeads bearing epoxy functionality on surfaces thereof and having a narrow particle size distribution, such that the particle size of greater than 90% of the polymeric microbeads in said population is equal to Â±20% of the mean particle size, said epoxy functionality arising from one or more multifunctional epoxy monomers chosen from the group consisting of 3,4-epoxycyclohexyl methyl-3â€²,4â€²-epoxycyclohexane arboxylate, bis-(3,4-epoxycyclohexyl) adipate, 4-vinylcyclohexene dioxide, epoxy silicone resins, limonene dioxide, dicyclopentadiene dioxide, bisphenol-A diglycidyl ether, bisphenol-F diglycidyl ether, 1,4-butanediol diglycidyl ether, diglycidyl ethers of tetrabromo-bisphenol-A, epoxy cresol novolacs, epoxy phenol novolacs, and diglycidyl phthalate.
