The polymerization of 2,2-dimethyloxirane should be described by anionic mechanism. Concept Introduction: Anionic polymerization: Initiator will be a nucleophile which reacts with the monomer to form a propagating site that is an anion and the initiator can be compounds like sodium amide or butyllithium. Nucleophile will attack on the alkene and the alkene contains a substituent that can withdraw electrons by resonance.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

Interpretation Introduction

Interpretation:

The polymerization of 2,2-dimethyloxirane should be described by cationic mechanism.

Concept Introduction:

Cationic polymerization:

The polymerization in which an electrophile acts as an initiator and adds to the monomer which leads to the formation of a carbocation.

The initiator widely used is a Lewis acid and in the polymerization the electrophile adds to the sp2 carbon bonded to the most number of hydrogens.

5.2 A batch of poly(butylene terephthalate), PBT, is made by reacting butylene glycol (also known as 1,4-butane diol) with terephthalic acid, see example 2.4C. A total of 5 moles of polymer is made. The mixture contains 1.06 moles with a molecular weight of 207,900, 0.65 moles with a molecular weight of 210,100, 0.54 moles with a molecular weight of 211,420, 1.13 moles with a molecular weight of 212,080, 0.77 moles with a molecular weight of 215,160, and 0.85 moles with a molecular weight of 480,920. (Note: the above means that there are 1.06 moles of chains that have the same degree of polymerization to give the MW of 207,900, and similar for each of the other entries)
