The copolymers of the invention are made from .alpha.,.beta.-unsaturated dicarboxylic acid esters and .alpha.-olefins. The .alpha.-olefins employed have 8 to 24 C-atoms and the .alpha.,.beta.-unsaturated dicarboxylic acid esters are made solely from ethoxylated alcohol with a degree of ethoxylation of 1 to 45. Also disclosed is a process for the production of these copolymers, in which either .alpha.-olefin having 8-24 C-atoms is copolymerized with .alpha.-.beta.-unsaturated dicarboxylic anhydride or .alpha.-.beta.-unsaturated dicarboxylic acid at temperatures of 80.degree.-210.degree. C. in the presence of a peroxide catalyst in an inert gas atmosphere, along with esterification with ethoxylated alcohol having a degree of ethoxylation of 1-45 in the mole ratio of 1:1 to 1:2 .alpha.-.beta.-unsaturated dicarboxylic acid or anhydride : ethoxylated alcohol, or by copolymerizing .alpha.-olefins having 8-24 C-atoms and .alpha.-.beta.-unsaturated dicarboxylic acid ester having ethoxylated alcohol with a degree of ethoxylation from 1 to 20 as alcohol component at temperatures of 140.degree.-210.degree. C. in the presence of a peroxide catalyst in an inert gas atmosphere. The copolymers are preferably used as lubricant for the shaping treatment of thermoplastic plastics.

This disclosure relates to a process for forming plastics from a melt of a mixture of plastics, stabilizers, antioxidants and lubricants, wherein the lubricants comprise a derivative of a copolymer of unsaturated polycarbonic acids or the anhydrides thereof and .alpha.-olefins having an average of at least 28 carbon atoms.

Shaping of plastic materials containing polymeric lubricant

There is provided a temperature indicating device such as a thermometer having a thermally conductive foil as a carrier layer, the carrier layer having one or more cavities formed by depression in the foil material. The depressions are filled with solid mixtures which melt at predetermined temperatures and are composed of ortho-chloronitrobenzene, ortho-bromonitrobenzene, and a dyestuff. A transparent cover layer seals the cavities and their contents. The transparent cover layer and carrier layer are bonded to each other by means of a pressure-sensitive adhesive which includes polyisobutylene.

Temperature indicating device using a pressure sensitive polyisobutylene

There is provided a time temperature device having an indicator layer which visually indicates the lapse of a time temperature integral. A signaling component is provided which, upon contact with the indicating layer, causes the indicator layer to undergo a visually perceptive change. The device further includes a reservoir for the signaling component, including a first backing and adhesive layer containing an adhesive substance. The adhesive layer is positioned between the indicating layer and the first backing.

Time temperature indicating device

A novel antioxidant composition and a method for making the same is disclosed. Said composition comprising, ##STR1## wherein R.sub.1 and R.sub.2 independently are selected from the group consisting of tertiary butyl, isopropyl, cyclohexyl, and phenyl, and R.sub.3 is a substituted triazine of the formula, ##STR2## wherein R.sub.4 and R.sub.5 independently are selected from the group consisting of organic radicals having at least one non-aromatic carbon atom, which non-aromatic carbon atom is attached to an oxygen atom connecting said radical with the triazine group.
