Document Summary
Called subunits or building blocks : monomers are all connected to one another. Process is called ________________: anywhere from __________ atoms per monomer. High-density polyethylene (hdpe: ________________ carbon chains, ____________ closely together, crystalline structure, 0. 94-0. 96 g/cm3. Low-density polyethylene (ldpe: _____________ carbon chains, less __________, waxy. Copolymer lldpe: lldpe = linear low density polyethylene, mixture of __________ and ________, hybrid , two different monomers, more branching than hdpe, less branching than ldpe. Thermoplastic polymers: when heated, these polymers can ____________ Addition polymerization: one type of polymerization reaction. " other types are condensation and free radical: the same atoms that are in the monomer are the same atoms that end up in the polymer. " what goes in = what comes out. Addition polymerization example: polypropylene: start out with propylene subunit: __________, remove double bond and attach monomers. Addition polymerization example: polystyrene: start with subunit styrene, attach together. Addition polymerization example: polyvinyl chloride (pvc: monomer (common name): vinyl chloride.
