Additive Effects in Polymers

Additive Effects in Polymers Plastic polymers have chemical reaction properties similar to those of small molecules, though the polymers themselves are larger in size This means that a range of different factors, including thermal conditions, stress cracking, or the diffusion of chemical additives , can alter the molecular structure, and thus .Additives can affect the properties and quality of mortars as well as basic materials such as cement, gypsum or aggregat They are widely used in various types of construction products to improve their , Additives in Sorel Cement Based Materials - Impact Study.
