Which factor is likely to increase the molecular weight of a polymer during its synthesis?
In a polymer, the chain grows from an initiator that starts the reaction. Other options are incorrect because Temperature controls how fast molecules ...
In the synthesis of a polyester through condensation polymerization, how would an increase in the molar ratio of diol to dicarboxylic acid affect the molecular weight of the resulting polymer and the byproducts formed during the reaction?
When the diol amount is larger, there are more hydroxyl groups available to join with the acid groups. Other options are incorrect because Some think ...
During the condensation polymerization of a specific polyester, which of the following changes in reaction conditions is most likely to enhance both the polymer's chain length and the formation of methanol as a byproduct?
Increasing the temperature makes the reaction run faster. Other options are incorrect because Reducing pressure mainly helps remove gases like water v...
In the context of condensation polymers, how does an increase in polymer chain length typically influence the thermal stability compared to addition polymers?
Longer chains contain more bonds that can interact. Other options are incorrect because Some think chain length has no effect, but more length means m...
Which of the following industries predominantly utilizes condensation polymers for creating durable and weather-resistant coatings?
Construction uses condensation polymers, such as polyurethanes, to make coatings that stay strong and resist rain and sun. Other options are incorrect...
Which of the following materials is formed through condensation polymerization, and why does it belong in this category?
Kevlar is made when aromatic monomers link together while dropping water molecules. Other options are incorrect because The mistake is thinking polyet...
Arrange the following steps in the correct order of the condensation polymerization process leading to the formation of Kevlar: A) Monomers react to form dimers, B) Elimination of small molecules occurs, C) Long chain polymers are formed, D) Dimers combine to form larger chains.
First, the two building blocks called monomers join to make a dimer. Other options are incorrect because This answer puts the chain‑forming step after...
Which of the following statements are true regarding condensation polymerization and its applications? Select all that apply.
In condensation polymerization the reaction removes a tiny molecule such as water, which pulls the growing polymer chain tight and gives the material ...
Condensation Polymerization:Kevlar :: Addition Polymerization:?
Addition polymerization joins monomers by sharing electrons, so no small molecules are lost. Other options are incorrect because People may think wate...
What is a key characteristic of condensation polymerization compared to addition polymerization?
When two monomers link in condensation polymerization, they leave behind a small molecule like water or HCl. Other options are incorrect because A com...
