PKSC 2020 TEST 2 (Corrugated and Intro to Polymers)
1. cellulose, coal, petroleum, natural gases: Raw Material for Polymers
1.

2. gas: According to the US dept of energy:
Although crude oil is a source of raw material (feedstock) for making plastics, it is not the major source of feedstock for
plastics production in the US. Plastics are produced from natural , feestocks derived from natural gas processing,
and feedstocks derived from crude oil refining.
3. plastics, many, parts, polymerization: Molecular Structure of Polymers:
are polymers:
poly =
mer =
is required to turn one monomer into a polymer
4. addition, condensation: Polymerization:
Two kinds of polymerization we care about:
: uses catalysts (PE, PP, PS, PVC)
1/8
, : Polyesters and poly-amide (nylon)
5. binding, HDPE, properties, linearity, copolymer: Addition Polymerization:
- catalysts help create sites for polymerization
- chromium-based or silica supported are used for
- different catalysts can create different molecular weight polymers and different
- metallocene catalysts (zirconium and titanium) creates in polyolefins
- more than one monomer might be used to create a
6. catalysts, acids, alcohols, amines: Condensation Polymerization:
are not needed: monomers with functional (reactive) groups are used
-
-
-
- water must be removed for the reaction to continue
7. covalent, within, atoms, strongest, electrons, positive, negative, polarity: Bond-
ing Forces:
2/8
