Abstract
The invention provides a class of polymeric materials being ABA tri-block or AB di-block, comprised of biodegradable segments and poly(propylene oxide) (PPO) segment and uses thereof.
Claims15
A solid polymer comprising a plurality of ABA tri-blocks, wherein A is a biodegradable segment consisting of poly(caprolactone) (PCL) and B consists of a polypropylene oxide) (PPO) segment, wherein, in the polymer, the tri-blocks are linked to one another via a urethane linkage, which urethane linkage optionally includes a chain extender between urethane groups;
- and wherein each tri-block has a molecular weight of between 2 KDa and 5,000 Kda.
