Abstract:
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.
Abstract:
A polyamide composition comprises a polyamide, an anhydride-functional copolymer reactive with the polyamide, and a poly (ethylene-co-methacrylic acid) ionomer. A pneumatic tire assembly includes an inner liner which is formed from the polyamide composition. The inner liner comprises the reaction product of the polyamide and the anhydride-functional copolymer, as well as the (ethylene-co-methacrylic acid) ionomer.
Abstract:
A composition comprises polyalkylene terephthalate and terpolymer of alkylene diol, isophthalic acid and terephthalic acid, and polyalkylene terephthalate reinforcing fiber. The composition may be used to form an article, alone or with other thermoplastic material, at lower processing temperature, with higher melt flowability. The article formed is characterized with lower warpage and improved mechanical properties. The article may be useful for automotive, electrical, household, construction, and industrial applications. A method of preparing such thermoplastic polyester is also disclosed.
