Abstract

"ARTIGOS ABSORVENTES QUE COMPREENDEM COMPOSIçõES DE MISTURA DE POLIéSTER BIODEGRADáVEL". A presente invenção refere-se a composições de mistura de poliéster alifático biodegradáveis resistentes e dúcteis e a métodos para a preparação de tais composições. A invenção refere-se a produtos compostos por tais composições de mistura, incluindo, mas não se limitando a, películas, fibras, elementos não-trançados, folhas, revestimentos, aglutinantes, espumas e produtos moldados para embalagem. Os produtos exibem uma combinação desejável de alta resistência, ductilidade e robustez, e mantêm a flexibilidade, biodegradabilidade e capacidade de compostagem. A presente invenção também refere-se a artigos absorventes (por exemplo, fraldas, absorventes higiênicos, forros de calcinhas, etc.) que compreendem uma camada superior permeável a líquidos, uma camada de suporte impermeável a líquidos que compreende uma película compreendendo as composições de mistura de poliéster da presente invenção e um núcleo absorvente posicionado entre a camada superior e a camada de suporte. A mistura de poliéster da presente invenção compreende: (a) um copolímero compreendendo duas unidades monoméricas de repetição aleatória, em que a primeira unidade monomérica de repetição aleatória tem a estrutura: em que R^ 1^ é H, ou C1 ou C2 alquila, e n é 1 ou 2. A segunda RRMU compreende pelo menos um monómero selecionado do grupo que consiste nas estruturas (II) e (III): em que R^ 2^ é uma C3-C19 alquila ou C3-C19 alquenila,e em que m varia de 2 a cerca de 16; sendo que pelo menos cerca de 50 % em mol do copolímero compreende RRMUs que têm a estrutura da primeira RRMU da fórmula (1) e em que o poliidroxialcanoato está presente a um nível de pelo menos cerca de 20%, em peso, do total do poliidroxialcanoato e do policondensado de éster alifático. em que R^ 1^ é H ou uma C~ 1-2~ alquila e n é 1 ou 2; e a segunda unidade monomérica de repetição aleatória tem a estrutura: em que R^ 2^ é uma C~ 3-19~ alquila ou alquenila; e (b) um policondensado de éster alifático sintetizado de um álcool poliídrico alifático e um composto de ácido policarboxílico alifático.
