Abstract
Official abstract text for this publication.
The disclosed technology relates to a novel coupled 6-amino uracil derivative, and the use of the coupled 6-amino uracil derivative as a stabilizer in halogen containing polymer compounds. In particular, the disclosed technology relates to the use of a coupled 6-amino uracil derivative as a stabilizer in vinyl chloride compounds, such as, for example, chlorinated polyvinyl chloride (CPVC) compounds.
First claim
Opening claim text (preview).
What is claimed is: 1. A rigid chlorinated vinyl chloride (“CPVC”) composition comprising (a) a CPVC resin, and (b) 0.1 to 1.75 phr of a stabilizer comprising a 6-amino coupled N-functionalized uracil derivative of formula where n is 1, R 1 is a C 1 -C 18 polyamine or C 1 -C 18 polyamine polyol, and R 2 and R 3 can be, separately, a C 1 -C 18 alkyl, C 1 -C 18 alkyl-ester, C 1 -C 18 alkyl-ether, or C 1 -C 18 alcohol. 2. The rigid CPVC composition of claim 1 , wherein the stabilizer further comprises at least one of zeolite or a C6 to C12 metal carboxylate. 3. An extruded pipe comprising the rigid CPVC composition of claim 1 . 4. A fitting for joining pipe sections comprising the rigid CPVC composition of claim 1 . 5. A method of stabilizing a rigid CPVC composition comprising employing in the rigid CPVC composition 0.1 to 1.75 phr of a 6-amino coupled N-functionalized uracil derivative.
