Re: [BKARTS] Questions about methyl cellulose

I would think that possible acidity would also depend on the degree of substitution in the cellulose polymer - it differs from normal cellulose in that some quantity of the -OH groups in the cellulose have been manipulated into -OCH3 groups and there's a range of possible substitution values.
