Abstract
The metal oxide vulcanization of polychloroprene in the presence of amidine compounds, but in the absence of magnesium oxide, leads to vulcanizates which are capable of withstanding high temperatures, even under dynamic stress.
Claims4
A process for the vulcanization of polychloroprene in the presence of
- i) 0.5 to 20% by weight metal oxide and
- ii) organic vulcanization accelerator,
- characterized in that
- a) the metal oxide i) is free from magnesium oxide and
- b) the organic vulcanization accelerator contains 0.2 to 0.6% by weight of at least one amidine compound,
- the percentages being based on polychloroprene.
