A process for lessening shear-induced reduction of fiber length in a melt processable, fiber reinforced polymer composition, and compositions useful in and obtained from such process, comprising the steps of: admixing a first polymer, the first polymer being a thermoplastic polymer, with a second polymer being TLCP, and a reinforcing fiber; and subjecting the composition to shear, wherein the first and second polymers have melt processing ranges that overlap over an overlapping melt processing range; and the second polymer is partly immiscible with or immiscible with the first polymer when mixed with the first polymer within the overlapping melt processing range.

Disclosed is a process for removing acetaldehyde from polyester which comprises the steps of

Process for producing polyester articles having low acetaldehyde content

Disclosed is an improvement in a process for producing branched polyesters wherein a precursor polyester is first formed and subsequently the precursor polyester is formed into particles and further polymerized in the solid state, wherein the improvement comprises contacting the particles while at a temperature of about 140.degree. to about 2.degree. C. below the melting point of the polyester with the vapor of water or an organic compound having at least one OH group.

Production of branched polyesters

Disclosed is an improvement in a process for producing linear polyesters wherein a precursor polyester is first formed and subsequently the precursor polyester is formed into particles and further polymerized in the solid state, wherein the improvement comprises contacting the particles while at a temperature of about 140.degree. to about 2.degree. C. below the melting point of the polyester with the vapor of water or an organic compound having at least one OH group.

Production of polyesters and polyester articles having good clarity

Disclosed is a process for producing copolyesters having repeat units from a dicarboxylic acid component comprising at least 90 mol % terephthalic acid and a glycol component comprising about 10-95 mol % 1,4-cyclo-hexanedimethanol and from about 90-5 mol % ethylene glycol comprising reacting the dicarboxylic acid component and the glycol component at temperatures sufficient to effect esterification or transesterification and polycondensing the reaction product in the presence of a catalyst and inhibitor system consisting essentially of Mn, Zn, Ti, Ge and P, all parts by weight based on the weight of the copolyester.
