PROCESS FOR THE PREPARATION OF A POLYSULFIDE |
摘要 |
Pre-polymer according to structure (I) X-(R2-O)n-CH2-O-(R1-O)m-CH2-(O-R2)p-X (I) wherein R1 and R2 can be the same or different and are selected from alkane chains containing 2-10 carbon atoms, X is a halogen atom, and n, m, and p are integers that can be the same of different and have a value in the range 1-6. The use of this pre-polymer in the preparation of a liquid polysulfide polymer allows better control over the sulfur and oxygen content and the polarity of the resulting polymer. |
