Pemulen™ polymers are high molecular weight, crosslinked copolymers of acrylic acid and C10-C30 alkyl acrylate. They are primarily used to form stable oil-in-water emulsions . Pemulen polymers contain both hydrophobic and hydrophilic portions within the molecule. The hydrophobic portion of the polymer adsorbs at the oil phase and the hydrophilic portion swells in the water forming a gel network around the oil droplets to provide exceptional emulsion stability.
Pemulen polymers form stable oil-in-water emulsions with no or low levels of co-surfactant. The co-surfactant enhances end product stability. Pemulen polymers provide efficient suspension and stabilization of insoluble materials and particles. These polymers provide shear thinning rheology which enables easy pumping and spraying of finished end products.
