WebThermoplastic Polymers Properties. Many thermoplastic polymers are reinforced with fibres. Reinforcement is used to improve physical properties – specifically heat deflection temperature. Glass fibres are the most commonly used reinforcing material. The wear resistance and abrasion resistance of thermoplastic polymers are improved by the use ... WebCarboxylic acids are organic compounds that contain a carboxyl functional group (-COOH). They are widely used in the production of various materials, including polymers. Polymers are large molecules made up of repeating units called monomers. Carboxylic acids can be used as monomers or as a reactant in the production of polymers. In this article, we
