Hello. This is Martin Matushek from M2 Polymer Technologies. We are experts in super absorbent polymer chemistry. We sell most of our products for industrial and environmental waste applications. The first patent for SAP was issued in 1962 to the US Dept of Agriculture for use as water conservation in soil. The product used starch as the basis for the polymer and then grafted acrylamide and acrylonitrile monomers along the chain with crosslinking agents. Starch is made of repeating units of the sugar, glucose, and there are a lot of places to add things and to crosslink these polymer chains so they become and absorbent. SAP technology has changed a lot from that time. The basic idea behind any of these is to first crosslink polymer chains and then to partially neutralize some of the acid functions to create a diffusion gradient. It is this diffusion gradient that actually draws water molecules into the network of polymer chains and then hydrogen bonding holds the water tightly in place. Current superabsorbent technology no longer uses starch to form the main polymer chains. SAPs today typically use acrylic acid or acrylamide as the base monomers to form the polymer chains then they add crosslinking agents to bridge these chains and then they partially neutralize the acid groups to create the diffusion gradient. First…. What is a polymer? A polymer is a large molecule made up of repeating, smaller molecules called “monomers.” Most common plastics are polymers but there …
