  • Patent number: 11879072
    Abstract: Disclosed herein are styrene butadiene rubber latex compositions with high solids content and methods for making and using these compositions. The method for making the styrene butadiene rubber latex compositions can include mixing a seed, a styrene, an initiator, a base, a surfactant, and a solvent; adding a first portion of 1,3-butadiene to make a first reaction mixture; heating the first reaction mixture for a first reaction time to make a first styrene butadiene rubber latex; mixing the first styrene butadiene rubber latex, a styrene, a base, an initiator, a surfactant, and a solvent; adding a second portion of 1,3-butadiene to make a second reaction mixture; and heating the second reaction mixture for a second reaction time to make a second styrene butadiene rubber latex, where the second styrene butadiene rubber latex has a solids content higher than that of the first styrene butadiene rubber latex.
