Methods and apparatus for coating substrates. A die can be employed for extrusion coating an elongated substrate, where the die defines a coating cavity therein. The die can comprise a die block having a coating supply channel for supplying a coating material to the coating cavity. The die can further comprise a guide plug and a die plate removably coupled to the die block. The guide plug can comprise a substrate inlet having a non-circular lateral cross-section, and the die plate can comprise a substrate outlet also having a non-circular lateral cross-section. A coating system comprising such a die can operate to coat a substrate where the substrate can be pushed at least partially through the die and contacts the coating material therein.

This invention relates to a process for preparing foamable branched polyester compositions having increased melt viscosity and melt strength, and a reduced level of unreacted monomeric branching agent. The process involves melt blending (A) a composition containing a polyolefin and branching agent, (B) a nucleating agent either in powder form or (B') in the form of a composition containing a polyolefin and nucleating agent, and a polyester.

Foamable polyester compositions having a low level of unreacted

The present invention relates to a process for copolymerizing a dicarboxylic acid, a dialkyl ester, and a diol in the presence of a transesterification catalyst. The process involves heating a mixture containing carboxylic acids and esters in excess diol at elevated temperatures in the presence of a transesterification catalyst and returning any vaporized diol to the reaction vessel until the theoretical amount of alcohol and/or water have been evolved. The alcohol and/or water of reaction is not allowed to return to the vessel. When the theoretical weight of alcohol and/or water is collected, the excess diol is removed and the polymerization is allowed to proceed.

Copolymerization of dicarboxylic acids and dialkyl esters of

Provided is indeno[1,2-.beta.] fluorene-6,12-diol, useful as an intermediate to polyesters. Also provided are derivatives of this compound and novel polyesters having residues of indeno[1,2-.beta.] fluorene-6,12-diol or its derivatives copolymerized therein and shaped or formed articles comprised of the novel polyesters.

Diols and polyesters made therefrom
