摘要:
The invention is a processing aid for thermoplastic polyesters which is a salt of a polycarboxylic acid or the salt of a polycarboxylic partial ester. The polycarboxylic acids are partial esters or sales of modified acids such as succinic acid, adipic acid, phthalic acid, citric acid, dicarboxylphenyl group and the like. The addition of the processing aid improves the slip and transparency.

摘要:
Radically post-crosslinked polymers are made by a process comprising the steps of: (1) forming a polyurethane (a*) by reacting a compound (a) with an aliphatic and/or an aromatic isocyanate and a compound (c) wherein compound (a) is the product of the reaction of an epoxidized fatty acid ester and/or an epoxidized triglyceride with acrylic acid and/or methacrylic acid and wherein compound (c) is a polyol ester having two or more C═C double bonds per molecule; (2) forming a crosslinked polyurethane by reacting the polyurethane (a*) with a radical initiator (b). The polymers are useful as components in composites comprised of natural and/or synthetic fibers.
