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 ...

Polyurethane prepolymer and aqueous polyurethane dispersion

2011
The invention relates to a polyurethane prepolymer prepared by reacting a mixture comprising a short-chain renew­ able diisocyanate and a long-chain renewable diisocyanate and one or more dials. The short-chain renewable diisocyanate has at most IO atoms and at most two ether group between the two isocyanate groups, and has at most 16 carbon atoms in ...
