Abstract

Se proporcionan composiciones de copolímero segmentado de polidiorganosiloxan poliurea procesable fundidos. Las composiciones comprendan alternar unidades polidiorganosiloxano blandas y unidades de residuos de diisocianato duras, el residuo de diisocianato es el isocianato menos los grupos - NCO, las unidades están conectadas juntas por medio de enlaces urea los cuales también proporcionan unidades duras. Las composiciones se preparan proporcionando continuamente al menos un diisocianato y al menos una polidiorganosiloxan diamina en el reactor bajo condiciones sustancialmente libres de solvente, dejando el diisocianato y la polidiorganosiloxan diamina reaccionar para formar un copolímero de polidiorganosiloxan poliurea, y transportando el copolímero desde el reactor.
