BRAINCAKECondensation Polymers
Revision notes for Condensation Polymers in AQA Chemistry (7405). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Condensation PolymersCondensation polymerisation joins monomers together with the loss of a small molecule, usually water (or hydrogen chloride if an acyl chloride is…
- PolyestersA polyester is a condensation polymer in which the repeating units are joined by ester links, -COO-.
- PolyamidesA polyamide is a condensation polymer in which the repeating units are joined by amide links, -CONH-.
- Nylon-6,6 and KevlarNylon-6,6 and Kevlar are both polyamides, but their monomers give them very different properties.
- Drawing Repeat UnitsAQA expects you to work in both directions between monomers and polymers: draw the repeating unit from the monomers, draw it from a section of…
- Hydrogen Bonding between Polymer ChainsThe intermolecular forces between polymer chains control properties such as strength and melting point.
- Biodegradability of PolymersA biodegradable polymer is one that can be broken down in the environment, for example by microorganisms, into smaller molecules.
- Disposal and Recycling of PolymersMost polymers end up as waste, and each method of dealing with them has advantages and disadvantages.
