Polyvinyl Acetate (PVA or PVAc) Polymer
By John A. Tuttle

Hi All,  Perhaps Paddy Handscombe needs to educate us here in America
about PVA glue.  Here's what I found at Wikipedia, and it explains why
we have a hard time understanding or believing what he says.

  Polyvinyl acetate, PVA, PVAc, poly(ethenyl ethanoate),
  is a rubbery synthetic polymer with the formula (C_4 H_6 O_2 )_n .
  It belongs to the polyvinyl esters family with the general formula
  -[RCOOCHCH_2 ]-.  It is a type of thermoplastic.

  It should not be confused with the related polymer polyvinyl alcohol,
  which is called PVA also.  (PVAc could be considered a technically
  correct abbreviation for polyvinyl acetate and would aid in avoiding
  such confusion).

  Polyvinyl acetate is a component of a widely-used type of glue,
  referred to variously as wood glue, white glue, carpenter's
  glue, school glue or PVA glue.
