Abstract
A process is provided which prepares an aqueous polymer emulsion containing an interpenetrating polymer network. This polymer emulsion is useful as a binder, adhesive or coating.
Claims24
Process for preparing an aqueous polymer emulsion comprising:
- (a) forming a first polymer emulsion containing an active crosslinking agent;
- (b) mixing a second monomer emulsion with the first polymer emulsion;
- (c) allowing the emulsion mixture to equilibrate;
- and
- (d) then polymerizing the emulsion mixture providing a first polymer network which is intertwined on a molecular scale with the 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 mixture.
A fiberfill product comprising a fiberfill bound by a binder comprising an aqueous polymer emulsion containing a first polymer network containing an active crosslinking agent which is 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 mixture.
