Chapter 29 - Organic Polymer Chemistry

Nylons

________ are polyamides that may be made from a diacid and a diamine, or from an amino acid, and are used as fibers.

term Plastic

The ________ refers to any polymer that can be shaped when hot and keeps its form when chilled.

Thermoplastics

________ are polymers that can be melted and become sufficiently fluid to be molded into shapes that retain their shape when cold.

air cyclone

A(n) ________ eliminates paper and other lightweight materials, while a detergent wash removes any leftover labels and adhesives.

HDPE

________ is utilized in the manufacture of items like as tableware and water bottles.

Mw

________ is computed by recording the total weight of each chain of a specific length, adding these weights, and dividing by the total weight of the sample.

LDPE

________ is a soft, translucent material that is blown into films using a blow- molding method.

Polyurethanes

________ are made up of flexible polymers.

solid form

In the ________, polymers are made up of both ordered crystalline domains (crystallites) and disordered amorphous domains.

diacids

Polyesters, which are generated from ________ and diols, are used to make textile fibers such as Dacron.

polydispersity index

A polymer's ________ is defined as the Mw /Mn ratio.

Mn

________ is calculated by counting the number of polymer chains of a specific molecular weight, multiplying each number by the molecular weight of its chain, adding these values, and dividing by the total number of polymer chains.

alkynes

Alkenes, ________, allenes, isocyanates, and cyclic compounds such as lactones, lactams, ethers, and epoxides are examples of monomers utilized in chain- growth polymerization.

Lexan

Polycarbonates, such as ________, are durable, transparent polymers with great tensile strength that are used to make anything from sporting equipment to unbreakable glass.

Metal catalysts

________, such as the Ziegler- Natta catalysts, can also be used to make high- density polyethylene (HDPE), which is tougher and more opaque than LDPE.

Polymers

________ are long- chain compounds formed by chemical processes that connect monomers.

Polymer architecture

________ consists of linear and branched chains, as well as comb, ladder, and star forms.
