The present invention relates to a polyester composition comprising: (A) 15 to 99 wt % of polyester blend of two or more polyesters based on the total weight of the polyester composition, (B) 0.05 to 5 wt % of a transesterification accelerator based on the total weight of the polyester composition, wherein the transesterification accelerator comprises alkali metal carbonate salt, alkali earth metal carbonate salt, alkali metal bicarbonate salt, alkali earth metal bicarbonate salt and combination thereof, (C) optionally a reinforcing filler, and (D) optionally further an additive. The present invention also relates to an article prepared from the polyester composition and a method of preparing the article.

Transesterification of polyesters

A polyamide composition with improved melt flow containing (A) 20 to 99.9 wt % of one or more polyamides independently selected from the group consisting of aliphatic polyamide, semi-aromatic polyamide, aromatic polyamide and their blends, (B) 0.1 to 10 wt % of one or more polyether polyols having a melting temperature below room temperature, (C) 0 to 70 wt % of one or more reinforcing agents, and (D) 0 to 50 wt % of one or more other additives, each based on the whole composition. A molding article produced from the polyamide composition also is disclosed.

Polyamide compositions with high melt flow and good mechanical properties

The present invention relates to a process for producing particles which comprise at least one halogen-free flame retardant and which comprise at least one metal oxide or semimetal oxide, where the particle can be a core-shell particle with flame retardant in the core and metal oxide or semimetal oxide in the shell, or a particle in which the distribution of flame retardant and a metal oxide or semimetal oxide is in essence homogeneous. The present invention further relates to particles comprising at least one halogen-free flame retardant and comprising at least one metal oxide or semimetal oxide, to a polymer molding composition comprising said particles and comprising at least one thermoplastic or thermoset polymer, and also to the use of said particles in polymer molding compositions or for providing flame retardancy to polymer molding compositions.
