Ocr a chemistry question

Hey guys,

I've been revising, and I'm now doing the industrial importance of alkenes. How much of it do we have to exactly know? What do we need to know bout Radical polymerisation and the Ziegler-Natta process? What are they?

Thank you!

You don't have to know very much - just what the processes are used for, and the conditions (temp, catalyst etc.) I don't have them to hand, but you can look them up fairly easily. I've never seen a question that has asked for much depth.

If you use the OCR textbook, on the top of each spread you will see some learning aims points listed. These points are the specification so it's what you need to know for the exam. If you go to the spread that has the Ziegler-Natta stuff, it will tell you what you need to know about them on the top of the page.

I was just revising polymerisation!
In the OCR AS Chemistry textbook, it is spread 2.1.17.
Pages: 134 - 135.

There are two types of polymerisation.

Radical Polymerisation
Zeigler-Natta Polymerisation/Process

What you need to know:

What are the conditions for both processes.
Specific Catalyst used in the Zeigler-Natta Process.
An advantage of the Zeigler-Natta Process over Radical Polymerisation. (This can be found out by reading the answer for Question 2 on the same spread)
