摘要： This invention relates to aliphatic copolyesters prepared from succinic acid (or derivatives thereof) and a process for the preparation thereof. The aliphatic copolyesters contain a second component, 1,4-butanediol, and a third component which is either a diacid or a diol (or derivatives thereof).

摘要： This invention relates to a blend comprising (a) 2 % to 98 % by weight of at least one ester of cellulose comprising an alkanoyl chain having from 1 to 10 carbon atoms, and having a D.S. of 2.3 to 3.0, and an inherent viscosity of 0.2 to 3.0 deciliters/gram as measured at a temperature of 25 °C for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, and (b) 98 % to 2 % by weight of at least one ester of cellulose comprising an alkanoyl chain having from 1 to 10 carbon atoms, and having a D.S. of 1.5 to 2.2, and an inherent viscosity of 0.2 to 3.0 deciliters/gram as measured at a temperature of 25 °C for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, said percentages being based on the weight of component (a) plus component (b).

摘要： Novel poly(3-hydroxyalkanoates), such as poly(3-hydroxybutyrate), and blends of these with other polymers are disclosed. A novel process for producing these poly(3-hydroxyalkanoates) is also disclosed which entails polymerizing one or more β-substituted-β-propiolactone(s) under polymerization conditions in the substantial absence of water in the presence of an anionic initiator.

摘要： This invention provides cellulose ester fibers having an intermediate degree of substitution per anhydroglucose unit (DS/AGU) along with pigments which act as photooxidation catalysts. The fibers are useful as filter materials for tobacco products. The filter materials thus provided are easily dispersible and biodegradable and do not persist in the environment.
