Abstract: A NEW CLASS OF BASIC POLYAMIDES HAVING A MOLECULAR WEIGHT BETWEEN ABOUT 2000 AND 200,000. THE POLYAMIDES ARE PREPARED BY FIRST REACTING AN ACRYLIC OR METHACRYLIC ESTER WITH A MONOAMINE AND THEN FURTHER REACTING THE OBTAINED PRODUCT WITH A POLYAMINE. THE POLYAMIDES ARE SUITABLE FOR USE AS TINCTORIAL MODIFIERS FOR POLYMERIC MATERIALS AND PARTICULARLY FOR CRYSYTALLINE POLYOLEFINS CONSISTING ESSENTIALLY OF ISOTACTIC MACROMOLECULES.

Abstract: Stabilized polytetrafluoroethylene emulsions particularly suitable for protective coating applications are produced by adding, to emulsions obtained from conventional emulsion polymerization of tetrafluoroethylene, a perfluoroketoether compound. The resulting emulsions are much more resistant to coagulation than are untreated emulsions when subjected to agitation or contacted with ionic materials such as acids and salts. More desirable coatings than heretofore possible, that are less subject to yellow discoloration occurring in conventional coatings and capable of being cast at greater thickness (of up to about 40 microns) without carcking, are obtained therewith. Concentrated polytetrafluoroethylene emulsions are produced by adding ionic material to the foregoing stabilized emulsions.

Abstract translation: 特别适用于保护涂层应用的稳定的聚四氟乙烯乳液通过向由四氟乙烯的常规乳液聚合获得的乳液中加入全氟酮醚化合物来制备。 当经受搅拌或与离子物质如酸和盐接触时，所得到的乳液比未处理的乳液抗凝性要好。 比以前可能的更理想的涂层，其在常规涂层中发生的黄色变色较少，并且能够以更大的厚度（高达约40微米）铸造而不会发生卡嗒声。
