what 2 factors of ligands orient monomers into position {Ans: shape and size hold monomers into position in ONE orientation}which substituent does the radical add to in the monomer? {Ans: adds to the LEAST substituted carbon of the C=C bond because this carbon is easier to approach and less hindered to produce a more stable radical intermediate}what is formed when a monosubstituted alkene monomer is polymerized? {Ans: a new chiral center is formed at every position where the substituent branches from the back bone of the chain}what two types of polymers can Ziegler-Natta catalysts be used on? {Ans: Isotactic and Syndiotactic (only stereoregular polymers)}what is chain propagation the same as? {Ans: some step as initiation in that monomers add in head to tail fashion with substituents present on alternating carbons in the chain}how step-growth polymers generally grow {Ans: by carbon-heteroatom bond formation}isotactic and syndiotactic are labeled as {Ans: Stereoregular}what 2 things stops chain growth polymerization? {Ans: 1. intervention 2. consumption of all available monomers}functionality of step-growth monomers {Ans: typically di or polyfunctional}polymer properties are strongly affected by: {Ans: 1. molecular weight (and distribution) 2. amount of branching (of the chain
