International Classification:

C08J 303

US Classification:

524829, 524800, 524871, 524874, 528423

Abstract:

The present invention concerns the preparation of polymers of low polydispersity and/or controlled molecular weight and architecture employing living free radical polymerization initiated by an alkoxyamine initiator or nitroxide plus, optionally, a free radical initiator, the polymer produced thereby; selected nitroxide and alkoxyamine initiators; and a process for making the initiators; the polymeric products being useful in protective coatings.

Appl. No.:

09/591452

Inventors:

Albert Gordon Anderson - Wilmington DE

Assignee:

E.I. du Pont de Nemours and Company - Wilmington DE

International Classification:

C09K 300

US Classification:

549200, 25218223, 528354, 528192, 528415, 549320, 549323

Abstract:

The rate of aminolysis of butyrolactones is predictably adjusted by attaching a substituent having a known field effect value (F) to the alpha position before reacting the substituted buytrolactone with an amine. The aminolysis product is a gamma-hydroxy amide. The resulting materials are useful as the cross-linking agents in a variety of coatings and coatings processes.

Appl. No.:

10/187502

Inventors:

Albert G. Anderson - Wilmington DE, US
Allisa Gam - Troy MI, US

Assignee:

E.I. du Pont de Nemours and Company - Wilmington DE

International Classification:

C25D013/10

US Classification:

204506, 204505, 523415, 528 45

Abstract:

An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a polyisocyanate crosslinking agent; wherein the improvement is the use of a polyisocyanate crosslinking agent having at least one crosslinkable morpholine dione group per molecule. Electrodeposited finishes are formed that have reduced volatile emissions and film weight loss when heated to cure.
