"He has developed the idea that new polymers -- large molecules made up of repeated simple molecules -- could be made from existing polymers. He and his team have used this idea to make a polymer which can be added to chewing gum. Cosgrove says: "Chewing gum is oil based, the new polymer makes it capable of absorbing more water." He adds that this makes the gum degradable and it gives the chewing gum a lower energy surface, meaning that when it sticks to a surface it is easy to pull off. It is, he says, green because it is completely solvent free."
