Abstract
A polymer composition stabilized against degradation during melt processing comprises a major amount of a polymer of carbon monoxide and at least one olefin and a minor amount of a stabilizer. The stabilizer can be a mixture of an aluminum trailalkoxide or hydrolysis product thereof with a amine, preferably a C.sub.12 to C.sub.20 amine; alternatively the stabilizer can be the reaction product of an aluminum alkoxide and an amine, preferably a C.sub.1 to C.sub.20 amine, or it can be a compound of the formula Al(OR.sup.x.sub.2)(NR.sup.3 R.sup.4.sub.y).
Claims13
A polymer composition stabilized against degradation during melt processing which comprises (a) a major amount of a polymer of carbon monoxide and at least one olefin;
- (b) a minor amount of a first stabilizer comprising an aluminum trialkoxide or an aluminum containing hydrolysis product thereof and (c) an amount in the range 0.05 to 3% by weight of the composition of a second stabilizer comprising an aliphatic mono-amine containing from 12 to 20 carbon atoms.
A polymer composition stabilized against degradation during melt processing which comprises (a) a major amount of a polymer of carbon monoxide and at least one olefin;
- (b) a minor amount of a first stabiliser comprising an aluminum trialkoxide or an aluminum containing hydrolysis product thereof;
- and (c) an amount in the range of 0.05 to 3% by weight of the composition of 1-octadecylamine.
A polymer composition stabilized against degradation during melt processing which comprises (a) a major amount of a polymer of carbon monoxide and at least one olefin, and (b) a minor amount of polymer stabilizer characterized in that the polymer stabilizer is the product obtainable by reacting at a temperature of 0.degree. to 120.degree. C. equal molar proportions of an aluminum alkoxide or an aluminum containing hydrolysis product thereof with a primary or secondary aliphatic mono-amine having up to 20 carbon atoms.
A polymer composition stabilized against degradation during melt processing which comprises (a) a major amount of a polymer of a carbon monoxide and at least one olefin and (b) a minor amount of a polymer stabilizer which is a compound of the formula Al(OR.sup.2).sub.x (NR.sup.3 R.sub.4).sub.y where x is 0 or 1-2, y is 3-x, and R.sup.2 is a C.sub.1 to C.sub.20 alkyl, phenyl or substituted phenyl group and the group NR.sup.3 R.sup.4 is derivable from a primary or secondary mono-amine, R.sup.3 and R.sup.4 are independently alkyl or aryl groups.
