Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
45 words
A method of forming a polymer latex, comprising the steps of: (I) providing a preformed emulsion polymer which is made from an organic monomer, a surfactant, an initiator and water, and (II) contacting said preformed emulsion polymer with an unsaturated alkoxy silane and additional initiator.
Claim 2
Independent Claim
45 words
A method of forming a polymer latex, comprising the steps of: (I) providing a preformed emulsion polymer which is made from an organic monomer, a surfactant, an initiator and water, and (II) contacting said preformed emulsion polymer with an unsaturated alkoxy silane and additional initiator.
Claim 3
Dependent Claim
20 words
The method of claim 1, where the unsaturated alkoxy silane comprises 0.1 to 20% by weight of the polymer latex.
Claim 4
Dependent Claim
20 words
The method of claim 2, where the additional initiator, comprises 0.1 to 50% by weight of the unsaturated alkoxy silane.
Claim 5
Dependent Claim
13 words
The method of claim 1 comprising the additional step of adding a filler.
Claim 6
Dependent Claim
13 words
The method of claim 1 comprising the additional step of adding colloidal silica.
Claim 7
Dependent Claim
13 words
The method of claim 1 comprising the additional step of adding a buffer.
Claim 8
Dependent Claim
21 words
The method of claim 1 comprising the additional step of heating the preformed emulsion polymer, unsaturated alkoxy silane, and additional initiator.
Claim 9
Dependent Claim
