Superabsorbent and elastic polymeric material including polyethylene glycol and polytetramethylene ether glycol soft segments and methods of making same

摘要

A superabsorbent and elastomeric thermoplastic polymer includes soft segments and hard segments which contribute to the functionality of the polymer. The soft segments have a molecular weight in the range from about 600 to about 20,000 and are selected from the group of PEG, PEO, PTMEG, PPG and PPO. The hard segments are selected from the group of polyurethanes, polyamides, polyesters, polyureas, and combinations thereof. The soft and hard segments are covalently bound together by means of urethane, amide, ester or secondary urea linkages or combinations.
