https://doi.org/10.1007/978-94-011-7245-5 together so as to form a nonreducing polyhydroxy material. Because of the many hydroxyl groups, starch has a high affinity for polar substances such as water or cellulose. Starch can be reduced to low molecular weight sugars by enzymes called ., or by acid hydrolysis.

World equilibrium and European securityne for elastomeric adhesives. Neoprene combines rapid bond strength, development with good tack or auto-adhesion, and resistance to degradation by oils, chemicals, water, heat, sunlight, and ozone. It is popular in numerous areas such as shoe sole attachment, furniture construction, automobile assembly, and a variety of construction applications.

Jacqueline Roddick,Nico van Niekerky were the only high-sulfur polymers available. The solid polysulfide polymers contained 37–82% bound sulfur, while the liquid polymers contain approximately 37%, which gives them their unique chemical properties.
