The correct option is A PHBV
Kevlar is also known as poly para-phenylene terephthalamide. It is an amide polymer which is obtained from co-polymerization of benzene-,4-diamine, and terephthaloyl dichloride. It is an extremely tough and resistant material. It is mainly used in bulletproof vests and fire-resistant clothing due to its nature and properties.
PHBV which is nothing but poly (3-hydroxybutyrate-co-3-hydroxy valerate). PHBV is produced by microbial fermentation and thus, it is a synthetic polymer. And also PHBV is completely biodegradable thermoplastic and it is a copolymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid. It is mainly used as packaging materials in orthopaedic devices and also used in controlled drug disease.
Glyptal is a type of polymer which is obtained from the co-polymerization of ethylene glycol and phthalic acid. It is mainly used in the manufacture of paints, lacquers, etc. It also acts as a binding material in paints, cement, etc.
Bakelite is a polymer which is obtained from the copolymerization of phenol and formaldehyde. It is the first synthetic plastic compound. It is one of the examples for thermosetting polymers and it is mainly used in automotive and industrial applications due to its high resistance to electricity.
Thus, the polymer used as packaging material in orthopaedic devices and for controlled drug disease is PHBV .
So, the correct answer is Option B.
