Crossword
Description

The formal name for a chain reaction polymerization. Addition
The formal name for a step-growth polymerization reaction. Condensation
The name for a molecule, atom or ion with unpaired electrons that initiates addition polymerization. Free Radical
A type of polymer with chains of two or more monomers. Copolymer
The name for a type of copolymer whereby monomers are arranged in turns. This is needed for crystalline polymer forms. Alternating
The second step in addition polymerization whereby the chain grows (the most amount of time is spent here). Propagation
A type of polymer described as "beads on a string with charms". Branched
A step in addition polymerization whereby two free radicals join to create a stable bond. Termination
The term that describes two equal forms of a benzene molecule when single and double bonds alternate around the ring (bond length is 1.5). Resonance
The name of the molecule composed of one benzene ring with one less hydrogen that is always attached to something else. Phenyl
Epoxies are an example of this type of plastic that decomposes before it melts. They are re-used as fillers. Thermoset
Polyethylene is an example of this type of plastic that can be remolded. Thermoplastic
The term to describe the chemical bonds that form between Polyvinyl acetate chains in Borax to produce silly putty. Cross-linked
The name for amorphous polymers with low glass transition temperatures (Tg). Elastomers
A type of plastic with holes between its cross-linked chains. This plastic can swell and absorb water or solvent. Gel
A type of test (qualitative analysis) whereby plastic samples are exposed to an open flame. Hint: A green flame indicates the presence of PVC. Beilstein
Plastic used for ketchup bottles and yogurt or margarine containers. It is identified by the Recycling Number "5". Polypropylene
Composed of amide monomers represented as HNC=O. Hint: Nylon 6 is an example of this polymer. Polyamide

Used to improve specific properties of plastics such as flexibility or colour, while maintaining other properties. These may migrate as the plastic ages. Additives
A residue that forms on the surface of plastics which is often oily. Blooming
A highly flammable material used as a transparent coating on photographs from 1889-early 1950s. One positive test to distinguish it from other materials is that it turns a deep blue colour in a solution of Diphenylamine with 90% Sulfuric Acid. Cellulose Nitrate
"Vinegar Syndrome" is a telling sign of the decomposition of this material also used to coat photographs starting in the 1920s. Cellulose Acetate
