Abstract: The present invention relates to a method for reducing an amount of glass filaments separating from pellets comprising a thermoplastic polymer sheath intimately surrounding the glass filaments. The method can include transporting the pellets through a piping system and/or by a vibrating conveyor means. The pellets have a length of at least 13 mm. The amount of glass filaments separating from the pellets when such pellets are subjected to repetitive mechanical loads in transportation is reduced as compared other pellets subjected to the same repetitive mechanical load, such that blocking caused by the glass filaments within the pellet transport system is reduced or eliminated as compared to transporting pellets having a length of less than or equal to 12.1 mm.

Abstract: The method disclosed herein relates to two stage catalytic processes for converting syngas to acetic acid, acrylic acid and/or propylene. More specifically, the method described and claimed herein relate to a method of producing acrylic acid and acetic acid comprising the steps of: a) providing a feedstream comprising syngas; b) contacting the feedstream with a first catalyst to produce a first product stream comprising C2-C3 olefins and/or C2-C3 paraffins; and c) contacting the first product stream with oxygen gas and a second catalyst, thereby producing a second product stream comprising acrylic acid and acetic acid, wherein there is no step for separating the components of the first product stream before the first product stream is contacted with the second catalyst.
