Method for making structured suspension PSA beads |
摘要 |
The invention relates to pressure-sensitive adhesive (PSA) structured bead, which has a distinct morphology, which is comprised of a copolymer which is characterized as a two-phase system wherein more rigid, thermoplastic segments (hydrophilic segments formed from the polymerization of water soluble monomer in the water-in-oil emulsion particles) provide discrete reinforcing micro-domains within a predominating continuous matrix formed by rubbery, viscoelastic polymer segments (formed from the polymerization of the ester and the polar monomer). The invention also relates to a method of making the beads via a polymerization of a water-in-oil emulsion in a water suspension.
