The present invention relates to stabilizing compositions for chlorine-containing polymers and resins, which are substantially and preferably free from metals, and which contained at least one or more oxazole, thiazole or imidazole compounds of formula:
wherein X = O, S or NH,
and at least a co-stabilizer.
These compositions are particularly useful for the stabilization of PVC resins; the stabilized compositions can be advantageously used for manufacturing of pipes or fittings, compact or foamed sheets, films (rigid or flexible), profiles.
本发明涉及用于含氯聚合物和树脂的稳定化组合物,这些组合物基本上且最好不含金属,并含有至少一种或多种式中的噁唑、噻唑或咪唑化合物:
其中 X = O、S 或 NH、
和至少一种共稳定剂。
这些组合物特别适用于 PVC 树脂的稳定化;稳定化后的组合物可以很好地用于制造管材或管件、密实或发泡板材、薄膜(刚性或柔性)、型材。
