Patent ID: 7153915

Claim:
A precision fragmentation assemblage wherein said assemblage comprises: (A) a plurality of fragmentation domains; (B) one or more fragmentation zones; wherein said fragmentation domain comprises at least one first polymer; and wherein said fragmentation zone comprises: (i) one or more connecting phases; (ii) optionally, one or more pore phases; and (ii) optionally plural polymeric nanoparticles; and wherein: said connecting phase comprises at least one second polymer; said second polymer comprises at least one multi-ethylenically unsaturated monomer, present as polymerized units, in an amount of at least 0.05 percent by weight to 100 percent by weight, based on the weight of said second polymer; and said nanoparticles comprise at least one third polymer; and (C) one or more tether groups covalently bound to a polymeric chain, wherein said polymeric chain is a chain selected from the group consisting of said first polymer, said second polymer, said third polymer, and combinations thereof.
