Polyacetals having an improved maximum sustained-use temperature |
摘要 |
Polyacetal molding materials which contain, as a stabilizer, from 0.1 to 10% by weight of a melamine resin, the latter being a melamine-formaldehyde condensate, having a mean degree of polymerization of from 1.2 to 6.0 and a melamine:formaldehyde ratio of from 1:2 to 1:5.5, which has been partially etherified with a C1-C4-alkanol so that the ratio melamine:ether radicals is from 1:1.5 to 1:5.0 and the ratio melamine:free methylol groups is from 1:0.5 to 1:3. The molding materials can be converted to moldings which can be used industrially at elevated ambient temperatures.
