Which monomer is present in Bakelite?
Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer.
What is the monomer structure of polypropylene?
Polypropylene (PP) is a tough, rigid and crystalline thermoplastic produced from propene (or propylene) monomer. It is a linear hydrocarbon resin and its chemical formula is (C3H6)n.

What is Dynel made of?
A copolymer of acrylonitrile and vinyl chloride, Dynel shares many properties with both polyacrylonitrile (high abrasion resistance, good tensile strength) and PVC (flame resistance). It is an acrylic resin.
What are the monomers of Dextron?
Dextron is a polyacetic acid polyglycolic acid polymer. The monomers used are lactic acid and glycolic acid. It is copolymer and has ester linkage. It is used as friction modifier.
What is the monomer of PVC and Bakelite?
(i) The monomer of polyvinyl chloride is CH2 = CHCl vinyl chloride. (ii) The monomer of teflon is CF2 = CF2 tetrafluoroethylene. (iii) The monomers involved in the formation of bakelite are HCHO formaldehyde and C6H5OH phenol.
What is the monomer of melamine polymer?
formaldehyde
Common monomer of melamine is formaldehyde, HCHO. Melamine resin or melamine formaldehyde (also shortened to melamine) is a hard, thermosetting plastic material made from melamine and formaldehyde by polymerization.
What is the monomer of polyethylene?
ethylene
Low density polyethylene polymers are called homopolymers because they are produced with only one monomer (ethylene).
What type of polymer is polypropylene?
Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB), is a polyolefin or saturated polymer.
What are the monomers of PVC and Bakelite?
(i) Polyvinyl chloride (ii) Teflon (iii) Bakelite. 1) Polyvinyl chloride (PVC) – The monomeric unit present is vinyl chloride (CH2 =CH –Cl).
What is the monomer of nylon 66?
Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name.
What is dynel used for?
Dynel is a trade name for a type of synthetic fiber used in fibre reinforced plastic composite materials, especially for marine applications. As it is easily dyed, it was also used to fabricate wigs. The fashion designer Cardin used Dynel fabric to make a collection of heat-moulded dresses in 1968.
What does the word dynel mean?
Definition of dynel 1 : a fiber made in staple form from vinyl chloride and acrylonitrile and characterized by great resistance to burning. 2 : a yarn or fabric made of Dynel fiber.
Is Dextron a homopolymer?
Dextron is a copolymer and it is made by polymerization of two monomers.
Which of the following pairs of monomers is used for the preparation of Dextron?
– The Monomers used in the preparation of Dextron are Glycolic acid and Lactic acid.
What are the monomers of Bakelite and Teflon?
(ii) The monomer of teflon is CF2 = CF2 tetrafluoroethylene. (iii) The monomers involved in the formation of bakelite are HCHO formaldehyde and C6H5OH phenol.
