Abstract
A composition for stabilising halide-containing polymers, said composition comprising compounds represented by the general formula (I) wherein X, Y, and Z are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II) wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl group, A is oxygen (O) or sulfur (S); and wherein the dashed double line represents an optional double bond.

A composition comprising:
- a halide-containing polymer;
- and
- a stabilizer composition comprising one or more compounds represented by the general formula (I):
- wherein
- X, Y, and Z are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II)
- wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl,
- A is oxygen (O) or sulfur (S);
- wherein the dashed double line
- represents an optional double bond;
- and
- wherein the stabilizer composition is at least partially bound to the halide-containing polymer to thereby at least partly inhibit thermal degradation of said halide-containing polymer.
A polyvinyl chloride resin composition comprising polyvinyl chloride resin and a heat stabilising effective amount of a stabilizer composition comprising compounds represented by the general formula (I):
- wherein X, Y, and Z are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II)
- wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl,
- A is oxygen (O) or sulfur (S);
- wherein the dashed double line
- represents an optional double bond;
- and
- wherein the stabilizer composition is at least partially bound to the polyvinyl chloride resin to thereby at least partly inhibit thermal degradation of said polyvinyl chloride resin.
A method of preparing stabilised halide-containing polymers comprising the steps of:
- mixing a material comprising halide-containing polymer resin and a composition according to a stabilizer composition comprising compounds represented by the general formula (I):
- wherein X, Y, and Z are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II)
- wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl,
- A is oxygen (O) or sulfur (S);
- wherein the dashed double line
- represents an optional double bond;
- and
- heating the mixed material for a period so as to at least partially bind the halide-containing resin and stabiliser composition.
A composition comprising;
- a halide-containing polymer;
- a stabilizer composition comprising one or more compounds represented by the general formula (I):
- wherein
- X, Y, and Z are each independently selected from the group, consisting of hydrogen, alkyl, alkenyl, alkynyl, amino, and groups having the structure (II)
- wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, phenylalkyl and aryl;
- A is oxygen (O) or sulfur (S);
- and
- wherein the dashed double line
- represents an optional double bond;
- and
- a metal perchlorate salt,
- wherein the stabilizer composition is at least partially bound to the halide-containing polymer to thereby at least partly inhibit thermal degradation of said halide-containing polymer.
