Document Summary
Thermoplastic polymers: w/ heat they can be reshaped and reshaped again after making. Chemistry exam 1 & 2 study guide (big 6) Thermosetting polymers: have crosslinks that make them stiff, and prevent them from being re-melted. Cross-links: covalent bonds, not recyclable, too stiff to stretch. Homopolymer: made from one type of monomer. Addition polymerization: monomers" double bond open up to form a continuous chain; reaction of monomers without the elimination of atoms; only have carbon in their backbones. Condensation polymerization: the polymer is not the only product - alcohol or amine & carboxylic acid or acid chloride; produces h2o or hcl. Monomer: small molecules used to synthesize polymers. Polymer: large molecules consisting of a long chain or chains of atoms covalently bonded together. Reaction mechanism: shows how e- move and atoms rearrange during a chemical reaction. Plasticizer: compounds that are added in small amounts to polymers to make them softer and more pliable (between polymer chains)
