Re: vbar of PEG

Hi Neil,

Here's a belated additional reply to your request for data about PEG 2000.

Amongst the replies to a reqeust I made to RASMB for PEG info in Dec 1997,
I received data from Eckhard Goernitz as follows:

Mass of PEG (g/mol)		vbar (ml/g)
200			0.862
400			0.845
600			0.841
1500			0.838
4000			0.836
10000			0.834
20000			0.832

I was advised that these are in accordance with results in the following paper:

L. Lepori & V. Mollica, J. Polymer. Sci. Polym. Phys. Ed., Vol 16 (1978)
1123-1134.

And these data also fit well with those that Tom Laue reported last week.

All the best-
Olwyn
