Short Answer
Expert verified
It is impossible to determine which compound 'Q' is among these four polymers without additional information about its properties.
Step by step solution
01
Understanding Nylon-6 properties
Nylon-6 is a synthetic polymer, also known as polycaprolactam. It is a widely used fiber in textiles and other applications. It has high strength, elasticity, and abrasion resistance. However, it has a low melting point and is prone to hydrolysis in hot and humid conditions.
02
Understanding Nylon-6,6 properties
Nylon-6,6 is another synthetic polymer and similar to nylon-6 in its properties, but it is derived from different precursors. It has slightly higher mechanical strength, melting point and resistance to hydrolysis than nylon-6. Like nylon-6, it is used mostly in the production of textiles, automotive parts, and more.
03
Understanding Polyester properties
Polyester is a large group of polymers with a wide variety of applications, including clothing, furnishings, films, fibers, and industrial materials. Polyester properties can vary widely depending on the specific polymer, but generally, they have good mechanical properties, high strength, good thermal stability and resistance to hydrolysis.
04
Understanding Glyptal properties
Glyptal is a type of alkyd resin polymer, made by condensation of phthalic anhydride and glycerol. It is used mainly in surface coating and insulation materials for electrical applications. The polymer has good adhesion, high resistance to oil, good thermal stability, and electrical insulating properties.
05
Comparison of properties and final conclusion
From the analysis of properties of all four polymers, we see that each of them has its unique properties and specific applications. However, since there is no information given about the properties of compound 'Q' in the exercise, it is impossible to determine which compound 'Q' is among these four polymers.

Nylon-6 properties
Nylon-6, or polycaprolactam, is a prominent member of the nylon polymer family, widely recognized for its unique set of characteristics. Notably, this synthetic material exhibits strong durability and excellent elasticity, making it an ideal candidate for various textile applications. As a testament to its versatility, Nylon-6 maintains a commendable resistance to abrasion, a desired trait for materials subjected to frequent wear and tear.
Despite its commendable attributes, Nylon-6 isn't without its limitations. One such drawback is its relatively low melting point, which necessitates caution during thermal processing. Another challenge is its susceptibility to hydrolysis, particularly in hot and humid environments, which can compromise its physical properties over time. These factors must be considered when choosing Nylon-6 for specific applications, to ensure long-term performance and reliability.

Nylon-6,6 properties
Nylon-6,6, akin to its close relative Nylon-6, is a synthetic polymer that enjoys widespread utilization across numerous industries including textiles and automotive manufacturing. Its structure, derived from hexamethylenediamine and adipic acid, grants Nylon-6,6 a slightly enhanced set of properties when compared to Nylon-6.
The polymer stands out with its heightened mechanical strength, which aligns well with applications demanding robustness and durability. Additionally, the increased melting point of Nylon-6,6 extends its utility range to environments that may involve elevated temperatures. Also noteworthy is its greater resistance to hydrolysis, effectively lowering the risk of degradation in moist conditions. These properties collectively secure Nylon-6,6's position as a reliable material choice for enduring applications.

Polyester properties
Polyester serves as a wide-ranging family of polymers with a plethora of forms that cater to diverse applications such as clothing, furnishings, and industrial materials. What makes polyester especially advantageous is its robust mechanical properties that underpin a high degree of strength, ensuring durability across uses.
The thermal stability of polyester is another feather in its cap, providing confidence in its performance under heat stress. Furthermore, polyester's resistance to hydrolysis is a safeguard against the breakdown in wet conditions, a valuable quality for both outdoor wear and industrial applications. These attributes position polyester as an incredibly adaptable material, capable of meeting extensive demands in both consumer and technical fields.

Glyptal properties
In the realm of alkyd resin polymers, Glyptal distinguishes itself with its specialized uses, notably in surface coatings and electric insulation. Born out of the condensation reaction between phthalic anhydride and glycerol, Glyptal incorporates into its structure properties that align well with its applications.
One of Glyptal's standout features is its superior adhesion, which is quintessential for coatings that require strong surface bonding. Its high resistance to oil augments this property, making it a go-to option for protective coatings in environments with potential oil exposure. Glyptal's commendable thermal stability and electrical insulating properties also broaden its appeal, particularly in the electrical domain where such traits are non-negotiable for safety and function. Its dedicated attributes ensure Glyptal's place as a material of choice within its niche applications.
