摘要:
The invention relates to polymer-modified polyisocyanates and to polyurethanes prepared therefrom, and to their use in the production of polyurethane molded bodies. The polyisocyanates are modified with thermoplastic vinyl polymers having a number average molecular weight of from 15 to 90 kg/mol.
摘要:
The invention relates to a process for preparing solid, transparent to translucent polyurethane molded items which, due to their elastic and optical properties, can be used, for instance, as an alternative material to rubber.
摘要:
This invention relates to a process for producing polyester-polyurethane compositions, and to the stabilization thereof in relation to hydrolytic ageing phenomena by an active ingredient combination comprising compounds containing carbodiimides with lactone derivatives, to mouldings produced therefrom and to the use thereof for semi-rigid, solid and/or cellular mouldings.
