Title: Catalisadores suportados para a polimerização de olefinas de fase gasosa
Inventor: NEAL-HAWKINS KAREN L
IPC: C08F210/16
Filed: 2003-08-21
Abstract: "CATALISADORES SUPORTADOS PARA A POLIMERIZAçãO DE OLEFINAS DE FASE GASOSA". A presente invenção refere-se a uma polimerização de olefinas na presença de catalisadores suportados heterogêneos que é aperfeiçoada por meio da incorporação no catalisador suportado de um grupo hidrofóbico unifuncional que compreende uma porção hidrofóbica não contendo nenhum nitrogênio básico ou um grupo reativo univalente. O grupo hidrofóbico unifuncional reduz a laminação e a folha nos processos de polimerização de fase gasosa e melhora a morfologia do polímero e a densidade por volume nos processos de polimerização de pasta fluida, enquanto substancialmente mantém ou melhora a atividade de polimerização de catalisador.

Abstract: A method of improving the soil-repellant properties of fabrics such as forming fabrics used in papermaking and cellulose machines, and filter cloths used in pa;permaking and cellulose industries and related industries. The improvement in accordance with the invention is obtained in that the synthetic material from which these fabrics are manufactured, is given improved hydrophilic properties, which in turn is achieved in that the synthetic starting material, prior to being extruded, is mixed with polymers which are made up of monomers having hydrolizable side groups. The fabric manufactured from the synthetic material is treated in a manner known per se with strong bases and or/acids to hydrolize the side groups.
