Abstract
Low molecular weight alcohols and diols of the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are each independently selected from the group consisting of hydrogen, alkyl or aryl and R.sub.3 is an alkylene, arylene, alkenylene or alkynylene radical, Z is hydrogen, hydroxyl or an alkyl group substituted with a hydroxyl group, and x is zero or 1, with the proviso that the alcohols or diols contain from three to twelve carbon atoms and x is not zero when R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are all hydrogen and Z is hydroxyl, significantly reduce the viscosity of and metal salt precipitation from liquid lubricating stabilizer compositions.
Claims22
A liquid lubricating and stabilizing composition for addition to a rigid vinyl halide resin, which composition is and can remain a liquid at a temperature of 50.degree. C. or less for an extended period of more than one month without substantial precipitation of metal salt compounds therefrom, said composition comprising:
- (a) from about 0.5 to about 5.0 parts by weight of an oil derived essentially from petroleum, which oil is liquid at ambient room temperature and meets the criteria:
- (molecular weight.times.(% paraffin content.times.(10.sup.-4).gtoreq.2.0;
- (b) from about 0.1 to about 1.0 parts by weight of a liquid vinyl halide heat stabilizer;
- (c) from about 0.15 to about 1.0 parts by weight of a metal salt of acids selected from the group consisting of tall oil acid, rosin acid, unsaturated fatty acids, saturated neo fatty acids and naphthenic acids, and wherein the metal is selected from the group consisting of calcium, magnesium, zinc, barium and strontium, and
- (d) from about 0.1 to about 20.0% by weight based on the total weight of the composition of an alcohol or diol of the formula:
- ##STR9## wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are each independently selected from the group consisting of hydrogen, alkyl or aryl and R.sub.3 is an alkylene, arylene, alkenylene or alkynylene radical, Z is hydrogen, hydroxyl or an alkyl group substituted with a hydroxyl group, and x is zero or 1, with the proviso that the alcohols or diols contain from three to twelve carbon atoms and x is not zero when R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are all hydrogen and Z is hydroxyl.
A rigid vinyl halide resin composition comprising polyvinyl halide resin and from about 2 to about 6 parts by weight per hundred parts by weight resin of a liquid lubricating and stabilizing composition which is and can remain a liquid at a temperature of 50.degree. C. or less for an extended period of more than one month without substantial precipitation of metal salt compounds therefrom, said liquid lubricating and stabilizing composition comprising:
- (a) from about 0.5 to about 5.0 parts by weight of an oil derived essentially from petroleum, which oil is liquid at ambient room temperature and meets the criteria:
- (molecular weight).times.(% paraffin content).times.(10.sup.-4).gtoreq.2.0;
- (b) from about 0.1 to about 1.0 parts by weight of a liquid vinyl halide heat stabilizer;
- (c) from about 0.15 to about 1.0 parts by weight of a metal salt of acids selected from the group consisting of tall oil acid, rosin acid, unsaturated fatty acids, saturated neo fatty acids and naphthenic acids, and wherein the metal is selected from the group consisting of calcium, magnesium, zinc, barium and strontium;
- and
- (d) from about 0.1 to about 20.0% by weight based on the total weight of the liquid lubricating and stabilizing composition of an alcohol or diol of the formula:
- ##STR10## 10 wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are each independently selected from the group consisting of hydrogen, alkyl or aryl and R.sub.3 is an alkylene, arylene, alkenylene or alkynylene radical, Z is hydrogen, hydroxyl or an alkyl group substituted with a hydroxyl group, and x is zero or 1, with the proviso that the alcohols or diols contain from three to twelve carbon atoms and x is not zero when R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are all hydrogen and Z is hydroxyl.
