摘要:
An alkylphenol-free liquid polymeric phosphite is described of general Structure IV illustrated below wherein each R1, R2, R3 and R4 can be the same or different and independently selected from the group consisting of C1-20 alkyl, C3-22 alkenyl, C6-40 cycloalkyl, C7-40 cycloalkylene, C1-20 methoxy alkyl glycol ethers, C1-20 alkyl glycol ethers, and or Y—OH; Y is selected from the group consisting of C2-40 alkylene, C2-40 alkyl lactone, —R7—N(R8)—R9—, wherein R7, R8 and R9 are independently selected from the group previously defined for R1, R2, R3 and R4, now further including H; m is an integral value ranging from 2 to 100 inclusive; and x is an integral value ranging from 1 to 1,000. The alkylphenol-free liquid polymeric phosphite is useful in reducing phosphite migration within polymers.
摘要:
The invention relates to liquid polymer additive compositions comprising blends of phosphite esters selected from the group consisting of aryl phosphites, alkyl phosphites, aryl/alkyl phosphites, bisphenol-A phosphites, dialkylene glycol phosphites and polydialkylene glycol phosphites, pentaerythritol phosphites, p-cumyl phenol phosphites with from 50 to 800 ppm inclusive of zinc per 100 parts resin. The stabilizer is used as either a complete or a partial replacement of toxic-metal containing antioxidant stabilizer additives.
摘要:
Various phenol-free phosphites for use in PVC as an alternative to the conventional phenol-containing products phenyl diisodecyl phosphite and diphenyl isodecyl phosphite were tested. These phosphites utilize para-cumyl phenol-based derivatives in order to provide a phenol free derivative of the above mentioned conventional phosphites.
摘要:
The chlorination of paraffins is carried out in the presence of water and in the absence of an organic solvent. In this way, it is possible to prepare highly chlorinated paraffins in a simple manner. The presence of hydrochloric acid even at high temperatures, has no deleterious effect on the quality of the product. The separation of the chloroparaffin from the hydrochloric acid is very good. An emulsion layer which hinders the transport of the chloroparaffin into downstream equipment does not occur.
摘要:
A process for the chlorination of a paraffin wax is described which includes the steps of contacting the paraffin wax or partially chlorinated paraffin wax with chlorine wherein the improvement is the use of a non-ozone depleting aromatic solvent with a boiling point less than 180.degree. C., preferably less than 160.degree. C. and which is non-reactive to chlorine in a free radical chlorination environment, in contrast to typical C.sub.1 -C.sub.2 aliphatic solvents.
