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 50 kPa (0.5 atm) to 150 kPa (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; wherein the solvent free ethylene propylene diene terpolymer comprises: (i) 85 weight percent to 99.75 weight percent of a random covalently linked polymer with saturated polymer backbones of ethylene and propylene, the ethylene and propylene having weight ratios from 40:60 to 85:15 of ethylene: propylene respectively, and a molecular weight from 100000 Mw to 5000 Mw; and (ii) 0.25 weight percent to 15 weight percent of a non-conjugated diene component consisting of at least one of: a methylidene norbornene, a dicyclopentadiene, an ethylidene norbornene, a 1, 4-hexadiene, norbornadiene, and a vinyl norbornene; and 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. 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 50 kPa (0.5 atm) to 150 kPa (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; wherein the solvent free ethylene propylene diene terpolymer comprises: (i) 85 weight percent to 99.75 weight percent of a random covalently linked polymer with saturated polymer backbones of ethylene and propylene, the ethylene and propylene having weight ratios from 40:60 to 85:15 of ethylene: propylene respectively, and a molecular weight from 100000 Mw to 5000 Mw; and (ii) 0.25 weight percent to 15 weight percent of a non-conjugated diene component consisting of at least one of: a methylidene norbornene, a dicyclopentadiene, an ethylidene norbornene, a 1, 4-hexadiene, norbornadiene, and a vinyl norbornene; and (i) 85 weight percent to 99.75 weight percent of a random covalently linked polymer with saturated polymer backbones of ethylene and propylene, the ethylene and propylene having weight ratios from 40:60 to 85:15 of ethylene: propylene respectively, and a molecular weight from 100000 Mw to 5000 Mw; and (ii) 0.25 weight percent to 15 weight percent of a non-conjugated diene component consisting of at least one of: a methylidene norbornene, a dicyclopentadiene, an ethylidene norbornene, a 1, 4-hexadiene, norbornadiene, and a vinyl norbornene; and 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.
