Which type of polymerization involves the loss of a small molecule during the polymerization reactions? a) subtraction polymerization b) sequential polymerization c) addition polymerization d) condensation polymerization
What is one of the most common ways that the properties of a polymer can be altered?
Homework Answers
Answer is option (d) Condensation polymerization.
Condensation polymers are any kind of polymers formed through a condensation reaction, where molecules join together—losing small molecules as byproducts such as water or methanol.
A general example of condensation polymerization is as follows:
Cross-linking ability among the polymer chain is the most common way that changes the properties of a polymer. The substance made of molecules that are cross-linked is harder and less flexible than the one without crosslinks. The links stop the molecules moving over each other so the structure is more rigid.

Which of the following statements about polymers is/are correct? select all that apply. Condensation polymerization reactions produce small molecules, like H2O, as byproducts to the polymer formation Addition polymers must be made from monomers which have at least one double or triple bond somewhere in the molecule. Polypropylene and polyethylene are high molecular weight alkenes.

The process of forming a polymer from monomers is called polymerization. Polymerization is achieved through condensation reactions. Which of the following is true concerning the energy requirements of condensation reactions? Question 2 options: A) condensation reactions do not require the input of energy because they result in the formation of covalent bonds between monomers and result in the liberation of water B) the covalent bonds generated by condensation reactions are easily broken by water and thus do not require the...

The purpose of this experiment is to synthesize a polymer using a Gilch polymerization of 2,5- bis(bromomethyl) - 1 -methoxy-4-(2-ethylhexyloxy) benzene, to investigate the polymer's photophysical properties, and to understand the mechanism of the polymerization reaction. Introduction Poly(p-phenylene vinylenes), or PPVS, are highly luminescent polymers that are used for a variety of commercial applications. Their general structure is shown in Figure . PPVS can be synthesized via a number of routes, including a Gilch polymerization reaction, which will be used...
