摘要:
The present invention relates to a biphasic superabsorbent and partially biodegradable material comprising a biodegradable and/or compostable polymeric phase and a non-biodegradable superabsorbent cross-linked polymer phase. Furthermore, the present invention relates to a process for the production of said superabsorbent material and the use thereof to contain and/or absorb and/or separate liquids, in particular aqueous liquids, preferably contaminated ones, and/or biological fluids.
摘要:
The present invention relates to a polymer composition comprising at least 20.0 wt.-%, based on the total weight of the polymer composition, of at least one biodegradable polymer resin, from 0.1 to 20.0 wt.-%, based on the total weight of the polymer composition, of at least one polyolefin selected from polyethylene and/or polypropylene and from 5.9 to 60.0 wt.-%, based on the total weight of the polymer composition, of an inorganic filler material dispersed in the at least one polyolefin and the at least one biodegradable polymer resin, a process for the preparation of such a polymer composition, the use of an inorganic filler material for increasing the thermal stability and/or processability of a polymer composition, the use of the polymer composition for the preparation of an article as well as in a process selected from extrusion process, co-extrusion process, blown film extrusion process, cast film extrusion or sheet extrusion process, extrusion coating process, injection molding process, blow molding process, thermoforming process as well as an article comprising the polymer composition.
摘要:
Novel absorbable polymeric blends having bimodal molecular weight distribution are disclosed. The bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a bimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of unimodal or bimodal molecular weight distribution. Alternately, the bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a unimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of bimodal molecular weight distribution. The novel polymeric bimodal molecular weight blends provide medical devices having improved dimensional stability. Also disclosed are novel absorbable medical devices made from these novel bimodal polymer blends, as well as novel methods of manufacture.
摘要:
A biodegradable synthetic polymer material obtained synthetically and to which sucrose has been added is disclosed. A process for the preparation of a biodegradable synthetic polymer material is also disclosed which provides the steps of: a) causing the starting monomers to polymerise under the usual conditions of macromolecule organic chemistry, until reaching the desired molecular weight; b) mixing the polymer obtained and the sugar in the desired proportions; c) proceeding to the usual subsequent processing.
