Abstract
An adhesive composition is prepared containing an aqueous copolymer emulsion which contains a first polymer network which is intertwined on a molecular scale with a second polymer network.
Claims31
An adhesive composition comprising a protective colloid and an aqueous polymer emulsion containing a first polymer network which is crosslinked and which is mixed and intertwined on a molecular scale with a second polymer network, wherein the second polymer differs from the first polymer and the first polymer comprises 5 to 95% on a solids by weight basis of the emulsion and the monomers of the first polymer and second polymer are not readily copolymerizable.
An aqueous polymer emulsion comprising a first polymer network which is crosslinked and which is mixed and intertwined on a molecular scale with a second polymer network, wherein the second polymer differs from the first polymer, wherein the first polymer comprises 5 to 95% on a solids by weight basis of the emulsion and the monomers of the first polymer and second polymer are not readily copolymerizable.
An aqueous polymer emulsion prepared by the process comprising:
- a) forming a first polymer emulsion which is crosslinked;
- b) mixing a second monomer with the first polymer emulsion whereby an emulsion mixture of the first polymer emulsion and a second monomer emulsion is obtained;
- c) allowing the emulsion mixture to equilibrate;
- and
- d) then polymerizing the emulsion mixture providing a first polymer network which is mixed and intertwined on a molecular scale with the second polymer network, wherein the second polymer differs from the first polymer and wherein the monomers of the first polymer and the second polymer are not readily copolymerizable and the first polymer comprises 5 to 95% on a solids by weight basis of the emulsion mixture.
