Stabilized adhesive microspheres |
摘要 |
Stabilized microsphere adhesive composition comprising: a plurality of polymeric, elastomeric microspheres wherein the microspheres are the reaction product of reactants comprising polymerizable starting materials comprising at least one C4-C14 alkyl (meth)acrylate monomer and optionally at least one comonomer, at least one vinyl-unsaturated additive having both an ionic moiety and a hydrophobic moiety and containing at least 5 but not more than 40 carbon atoms in an amount about 0.1 to 3 parts by weight of the microspheres; optionally, a polymeric stabilizer in an amount of between about 0.1 and about 3 parts by weight per 100 parts by weight of the microspheres; a surfactant in an amount of no greater than about 5 parts by weight per 100 parts by weight of the microspheres; optionally a modifier, wherein the modifier is at least one of a chain transfer agent, a tackifier, a solvent or the like in an amount that is sufficient to provide microspheres with a n-heptane soluble portion in the range of 30-98%; and (f) an initiator in an amount effective to catalyze the polymerization reaction present in amounts ranging from about 0.1 to approximately 2 parts by weight per 100 parts by weight of the polymerizable monomer starting material.
