  • Photocrosslinkable block copolymers for hot-melt adhesives
    Patent number: 9587062
    Abstract: Disclosed is a method for formation of block copolymers using a Single Electron Transfer Living Radical Polymerization (SET-LRP) process. The process can be used to form di and tri-block copolymers from vinyl monomers. In one embodiment the SET-LRP process comprises initially forming a macroinitiator using SET-LRP to form a first block of a di or tri-block copolymer and then using SET-LRP to form additional blocks of the copolymer. The produced block copolymers have very narrow polydispersity indexes and controlled molecular weights. The process permits incorporation of photoinitiators in any of the block formation reactions. The method also includes purification processes that result in a block copolymer having very low color making it useful in a variety of applications. In one application block copolymers prepared according to the present process can be used in hot-melt adhesives.

  • Digital printing inks
    Patent number: 9587127
    Abstract: The acrylate monomers of the present invention, particularly o-phenyl phenoxyethyl acrylate, provide very fast curing, hard and solvent resistant digital printing inks, and yet are also still surprisingly flexible. These properties make for a technically superior alternative to the widely accepted very hard monomer isobornyl acrylate. O-phenyl phenoxyethylacrylate also has the additional benefit of being free from the strong odor associated with isobornyl acrylate.
