A Fast Room-Temperature Self-Healing Glassy Polyurethane.

Angewandte Chemie, 2021
Glassy polymer can hardly self-heal at room temperature because of their frozen polymer chains under such a state. Now, we designed and synthesized a colorless and transparent glassy polyurethane assembled using low-molecular-weight oligomers carrying a ...

POLYURETHANE ELASTOMERS

Polyurethanes, 2020
Polyurethane elastomers are classed [1, 2] as multiblock copolymers whose primary structure comprises soft segments, made up from a diisocyanate and long-chain polyol (chiefly a polyether polyol, polyester polyol or polycarbonate polyol), and hard ...

Microbial degradation of polyurethane, polyester polyurethanes and polyether polyurethanes

Applied Microbiology and Biotechnology, 1999
Polyurethane (PUR) is a polymer derived from the condensation of polyisocyanate and polyol and it is widely used as a base material in various industries. PUR, in particular, polyester PUR, is known to be vulnerable to microbial attack. Recently, environmental pollution by plastic wastes has become a serious issue and polyester PUR had attracted ...
