Germany Low Cost Anionic Polymer

However, the strategy remained expensive because of the high cost of polymer conditioners, especially in the early decades of polymer conditioner development. During World War II water-soluble polymers were used to stabilize soils for road and runway construction (Wilson and Crisp, 1975). Experimenta-

owing to their low cost as well as their claimed ability to polymerize primary acrylates at room temperature.
