Claim Text:
1. A solvent free method for making a solvent free ethylene propylene diene terpolymer latex formulation, the method comprising: a. blending water with 1 weight percent to 50 weight percent surfactant forming a solution; b. blending solvent free ethylene propylene diene terpolymer with the solution at a pressure from 0.5 atm to 1.5 atm without an applied vacuum to form a terpolymer mixture, wherein solvent free ethylene propylene diene terpolymer is 10 weight percent to 60 weight percent of the total terpolymer weight of a final solvent free ethylene propylene diene terpolymer latex formation; c. high shear mixing the terpolymer mixture at from 0.5 atm to 1.5 atm for 5 minutes to 24 hours at a temperature from 20 degrees Celsius to 100 degrees Celsius to form a final solvent free ethylene propylene diene terpolymer latex formation, wherein the final solvent free ethylene propylene diene terpolymer latex formation has a viscosity from 1 centipoise to 2000 centipoise; a density from 0.8 to 1.1; and a shelf life of from 7 days to 365 days without separating or stratifying.
