Copolymers and block-copolymers exist.
The newly introduced isotactic and syndiotactic PP with regular molecular arrangement exhibit greatly improved properties and is produced in part with new metallocen catalysts.
PPS ( polyphenylene sulfid )
www.reiss-lighting.deEs existieren Copolymere und Block-Copolymere.
Stark verbesserte Eigenschaften weist das neu eingeführte isotaktische und syndiotaktische PP mit regelmässiger, molekularer Anordnung auf.Es wird zum Teil mit den neuen Metallocen-Katalysatoren hergestellt.
PPS ( Polyphenylensulfid )
www.reiss-lighting.deMany copolymers are derived from it, most well-known being PS foam.
New, regularly formed PS structures form syndiotactic PS ( = SPS ) with higher crystallinity and a melt-temperature of 270OC.
PUR ( polyurethane )
www.reiss-lighting.deBekannt ist besonders auch der PS-Schaumstoff.
Neue regelmässig aufgebaute PS-Strukturen ergeben syndiotaktisches PS ( = SPS ) mit hoher Kristallinit und einer Schmelztemperatur von 270OC.
