Plastics Workbook - Materials Assignment

One atom of _______ will combine with four atoms of hydrogen to make methane.

carbon

Just as methane and carbon-tetrachloride are based on a foundation of carbon but are entirely different, most plastics are built on a ______ base, but are widely different in properties, performance, and cost.

carbon

A single part chemical is a ______.

monomer

A multipart chemical or compound is a _______.

polymer

Polymerization is

the process of combining several monomers to form a polymer

If two or more different monomers are put together by polymerization you get a _____

copolymer

If you think of a copolymer as a series of beads on a chain you can readily see that all of them (are/are not) alike.

are not

Is there high or low intermolecular attraction in balanced and unbalanced structures?

Balanced - low

Unbalanced - high

A plastic formed from a linear polymer could be compared to a handful of cooked spaghetti. Each strand, thogh small in diameter is (100s, 1000s) of units long.

1000s

In linear polymers we see a similar sticking or gluing of the chains, except that the adherence is the result of the intermolecular attraction, this occurs where each strand touches or crosses another. What is this called?

cohesion

The molecular forces that hold individual linear polymer links together are _____ bonds

primary

The bonds that hold one chain to another in crossing are ______ bonds

secondary

The (adhesive/cohesive) forces consisting of secondary bonds stick the strands or chains to each other to five the plastic its individual properties.

cohesive
