polyvinyl acetal

https://doi.org/10.1351/goldbook.15256
Polymer prepared by acetalization of poly(vinyl alcohol) with an aldehyde.
Notes:
  1. The name "polyvinyl acetal" is derived using both source- and structure-based principles: "polyvinyl" comes from the source polymer: poly(vinyl alcohol), and "acetal" indicates the structure of constitutional units that are present in the resulting modified polymer. This approach is reflected in commonly used trivial names of polyvinyl acetals given in the above examples below systematic names.
  2. A common polyvinyl acetal does not have the ideal structure shown above but it also contains a low fraction of unreacted hydroxy groups.
