What would happen to the properties of a monomer as it became a polymer?
What would happen to the properties of a monomer as it became a polymer?
Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. To qualify as an oligomer, the properties of the molecule need to change significantly if one or a few subunits are added or removed.
How do you break a polymer?
Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water,” a reaction in which a water molecule is used during the breakdown. During these reactions, the polymer is broken into two components.
Is a steroid a polymer?
Steroids are not considered true lipid polymers because their molecules do not form a fatty acid chain. Instead, steroids are composed of four fused carbon ring-like structures.
Who is the father of polymer chemistry?
Hermann Staudinger
What was the first synthetic polymer?
Bakelite
What did we use before plastic?
Before the invention of plastic, the only substances that could be molded were clays (pottery) and glass. Hardened clay and glass were used for storage, but they were heavy and brittle. Some natural substances, like tree gums and rubber, were sticky and moldable.
Why was Bakelite discontinued?
Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions. Its discovery is attributed to the German chemist A.
Is Bakelite still made today?
Bakelite is still produced. Used in manufacturing machinable phenolics or micarta. Bakelite is a generic named material based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride. Today it is available in many grades through specialty composite and plastics manufactures.
What property makes Bakelite so hard?
Statement 1: Bakelite is hard and has high melting point. Statement 2: Intermolecular forces of attraction in it are H-bonding.
Is Bakelite fire resistant?
Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity.
