Abstract: Novel organo(block-amide-siloxane)-(block-amide-imide) polymers are prepared by a novel process comprising contacting an organodicarboxyterminated imide with an organodicarboxyterminated polysiloxane in the presence of an organodiisocyanate coupling agent. The resulting polymers are high molecular weight polymers having essentially linear recurring units comprising short chain amide-imide polymer blocks having the general formulas:
OR,
AND A LONG CHAIN AMIDE-SILOXANE POLYMER BLOCKS HAVING THE FORMULA:
WHEREIN BOTH A AND B ARE POSITIVE NUMBERS, THE RATIO OF A/A+ B IS WITHIN THE RANGE OF FROM ABOUT 0.01 TO ABOUT 0.99, C IS A POSITIVE NUMBER WITHIN THE RANGE OF FROM ABOUT 0 TO ABOUT 500, AND X IS A POSITIVE NUMBER WITHIN THE RANGE OF FROM ABOUT 4 TO ABOUT 10,000. The novel polymers are readily dissolved in suitable solvents for the application of a protective polymer coating on wire and cable substrates, or for the application of polymer films which have improved adhesion to glass.Abstract translation: 新的有机（嵌段 - 酰胺 - 硅氧烷） - （嵌段 - 酰胺 - 酰亚胺）聚合物通过新的方法制备，包括在有机二异氰酸酯偶联剂存在下使有机二羧基封端的酰亚胺与有机二羧基封端的聚硅氧烷接触。 所得聚合物是具有基本线性重复单元的高分子量聚合物，其包含具有以下通式的短链酰胺 - 酰亚胺聚合物嵌段：

Abstract: IMIDATOSILANES ARE PREPARED BY REACTING AN IMIDATE WITH A CHLOROSILANE IN AN INERT ORGANIC SOLVENT AND IN THE PRESENCE OF AN AMINE ACID ACEPTOR. THE AMINE SALT WHICH IS FORMED AS A BY-PRODUCT OF THE REACTION IS REMOVED FROM THE IMIDATOSILANE WHICH IS FORMED BY EXTRACTING IT WITH WATER.
