Abstract
Mixtures comprising polyarylene sulfides and polyarylene sulfoxides or partially oxidized polyarylene sulfides containing sulfoxide groups can be thermally crosslinked in a targeted manner depending on sulfoxide content. A process for producing crosslinked polyarylene sulfide moldings is based on the use of the mixtures in the thermal shaping.
Claims18
A polymer mixture comprising
- (A) from 1 to 99% by weight of at least one polyarylene sulfide consisting essentially of (--S--A--) as repeating units in said polyarylene sulfide, and
- (B) from 1 to 99% by weight of at least one polyarylene sulfoxide consisting essentially of (--SO--A--) as repeating units in said polyarylene sulfoxide, both calculated on total weight of the polymer mixture and wherein A is an arylene radical.
The mixture as claimed in claim 11, which contains a thermal stabilizer, a UV stabilizer, antistatic agent, a flame retardant, a pigment, an inorganic filler, an organic filler or a mixture thereof.
