Must have been a formula change at some point.
Reminds of the issue with cellulose acetate-based film and tape. Most
conscientious people placed said objects in airtight storage containers,
which apparently is exactly the thing *not* to do. I'm not aware of any
process to reverse the decomposition.
Old plastics in general are a nightmare for museum conservators.

Haa. Ask the conservators at Bor?s museum about clothes made from
synthetic materials. They end up having to throw away designer clothes
from 60's and 70's due to the fact that the
materials disintegrates !
And nothing can really be done - no pesticides which can
prevent
plastics from disintegrating.
Bor?s museum due to the town's history as a clothing industry cluster
(think New York's cloth industry but of course smaller) has a large
collection of clothing.
