Abstract

"POLIORGANOSILOXANO, PROCESSO DE PREPARAçãO DE UM POLIORGANOSILOXANO, COMPOSTO PARA REALIZAçãO DE PROCESSO, UTILIZAçãO DE UMA QUANTIDADE EFICAZ DE UM POLIORGANOSILOXANO E COMPOSIçãO DE POLìMERO ORGANICO ESTABILIZADO CONTRA OS EFEITOS PREJUDICIAIS DO CALOR E DOS UV". A presente invenção refere-se aos poliorganosiloxanos lineares, cíclicos ou ramificados que têm por molécula pelo menos três motivos siloxilas, dos quais pelo menos um é um motivo funcional de fórmula (I), em que R^ 1^ represebta um radical alquila C1 a C4 ou fenila, X é um grupo monovalente contendo uma (ou mais) aminas(s) cíclicas(s) de fórmula (II), em que R é um grupo hidrocarbonado, U = -O- ou -NR^ '^ com R^ '^ sendo H ou um grupo hidrocarbonado, Z é um grupo tetraalquil, -2,2,6,6 piperidinila, x = 0 e 1; y = 0, 1 e 2; z = 1, 2 e 3; y + z = 3; y + z = 3; e a é 0, 1 e 2. A referida função amina cíclica pode ser uma função piperidinila, x = 0 e 1; y = 0, 1 e 2; z = 1, 2 e 3; y + z = 3; y + z = 3; e a é 0, 1 e 2. A presente invenção refere-se também à utilização de tais poliorganosiloxanos nos polímeros, especialmente para melhorar sua fotoestabilização. (I) (II)."POLIORGANOSILOXANE, PROCESS OF PREPARATION OF A POLIORGANOSILOXAN, COMPOUND FOR CARRYING OUT THE PROCESS, USE OF AN EFFECTIVE AMOUNT OF A POLIORGANOSILOXAN AND COMPOSITION OF THE ORGANIC POLYMER STABILIZED AGAINST THE EFFECT OF THE EFFECT OF THE EFFECT OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECT OF THE EFFECT OF THE EFFECTIVE OF THE EFFECTIVE OF THE EFFECT. The present invention relates to linear, cyclic or branched polyorganosiloxanes which have at least three siloxyl motifs per molecule, of which at least one is a functional motif of formula (I), wherein R1 represents a C1 alkyl radical C4 or phenyl, X is a monovalent group containing one (or more) cyclic amines (s) of formula (II), where R is a hydrocarbon group, U = -O- or -NR ^ '^ with R When H is a hydrocarbon group, Z is a tetraalkyl group, -2,2,6,6 piperidinyl, x = 0 and 1; y = 0, 1 and 2; z = 1, 2 and 3; y + z = 3; y + z = 3; and a is 0, 1 and 2. Said cyclic amine function can be a piperidinyl function, x = 0 and 1; y = 0, 1 and 2; z = 1, 2 and 3; y + z = 3; y + z = 3; and a is 0, 1 and 2. The present invention also relates to the use of such polyorganosiloxanes in polymers, especially to improve their photostabilization. (I) (II).
