PHASE SEGREGATED BLOCK COPOLYMERS WITH TUNABLE PROPERTIES |
| 摘要 |
Phase segregated block-copolymer based on repeating structural elements represented by formula I;;wherein PHA represents at least one block based on one or more α-hydroxy acids, PDAS represents a central block based on a dialkylsiloxane,;the PDAS block has a weight average molecular weight in the range of from 4000 to 10000,;the blocks PHA have a weight average molecular weight in the range of from 2000 to 10 000,;the phase segregated block copolymer has a weight average molecular weight of from 40 000 to 120 000. |

1. Phase segregated block-copolymer based on repeating structural elements represented by formula I wherein PHA represents at least one block based on one or more α-hydroxy acids, PDAS represents a central block based on a dialkylsiloxane, the PDAS block has a weight average molecular weight in the range of from 4000 to 10000, the blocks PHA have a weight average molecular weight in the range of from 1500 to 10 000, the phase segregated block copolymer has a weight average molecular weight of from 40 000 to 120 000. |
