摘要:
A multimodal polymer composition comprising: (A) a polypropylene homopolymer or a propylene random copolymer comprising propylene and up to 5 weight % of comonomer selected from ethylene and/or C4-10 alpha olefin; and (B) a random copolymer of propylene and comonomer selected from ethylene and/or C4-10 alpha olefin; wherein the total comonomer content of the polymer composition is at least 0.5 wt % and the melt flow rate of the polymer blend is at least 6 g/10 min when measured according to ISO 1133 at 230° C. and a load of 2.16 kg.

摘要:
A polyolefin construction comprising at least one polyolefin (PO) layer, a barrier layer for the polyolefin layer and a compatibiliser for the PO and the barrier layer, which compatibiliser enables the PO and barrier layer to adhere together, whereby the barrier layer comprises the compatibiliser; a blended barrier layer polymer and the barrier layer formed therefrom and a process for producing the polyolefin construction.
摘要:
The present invention relates to an antioxidant composition comprising (a) 0.01-0.5% by weight of sterically hindered phenolic compound, (b) 0.01-0.5% by weight of phosphorous compound, and (c) 0.01-1% by weight of sulphurcontaining compound. Said antioxidant composition reduces degradation of plastic materials during processing and end-use and thus, increases the long term thermal stability of those plastic materials. Moreover, this invention relates to methods for producing a final polymeric article with an increased long term thermal stability and stabilization against ageing by radical decomposition processes and polymeric intermediate materials as well as polymeric articles comprising the inventive antioxidant composition.
