SAGMENTED COPOLYMERS OF POLIDIORGANOXYLOXAN POLYUREA AND A PROCESS TO PRODUCE THEM. |
| abstract |
Compositions of cast processable polydiorganosiloxane polyurea polyurea are provided. The compositions comprise alternating soft polydiorganosiloxane units and hard diisocyanate residue units, the diisocyanate residue is the isocyanate minus the NCO-groups, the units are connected together by urea linkages which also provide hard units. The compositions are prepared by continuously providing at least one diisocyanate and at least one polydiorganosiloxane diamine in the reactor under substantially solvent-free conditions, leaving the diisocyanate and polydiorganosiloxane diamine to react to form a copolymer of polydiorganosiloxane polyurea, and transporting the copolymer from the reactor. |
