Definitions
- the present invention relates to a polyalkylene carbonate resin composition, and more specifically, to polyalkylene carbonate and polyketone, having excellent transparency and flexibility, oxygen barrier properties, mechanical and chemical properties, in particular excellent thermal stability It relates to a polyalkylene carbonate resin composition.
- Polyalkylene carbonate is an amorphous transparent resin and has characteristics such as excellent transparency, excellent flexibility and high oxygen barrier property.
- aromatic polycarbonate which is a similar series of engineering plastics, it has biodegradability and has no carbon residue since it is completely decomposed into carbon dioxide and water during combustion.
- the present invention is to provide a resin composition capable of maintaining the inherent physical properties of polyalkylene carbonate and having excellent thermal stability and applicable to various fields.
- the present invention provides a polyalkylene carbonaneart resin composition containing 1 to 100 parts by weight of polyketone, based on 100 parts by weight of polyalkylene carbonate.
- the polyalkylene carbonate may include a repeating unit represented by the following formula (1).
- R 1 to R 4 are each independently hydrogen, a linear or branched alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an alkenyl group having 1 to 20 carbon atoms, or a cycloalkyl group having 3 to 20 carbon atoms; Any two of R 1 to R 4 may be linked to each other to form a cycloalkyl group having 3 to 10 carbon atoms;
- n is an integer of 10-1, 000.
- Such polyalkylene carbonate is specifically, for example, polyethylene carbonate, polypropylene carbonate, polypentene carbonate, polynuxene It may be one or more selected from the group consisting of carbonates, polyoctene carbonates, polycyclonucleene carbonates and copolymers thereof.
- the polyalkylene carbonate may have a weight average molecular weight of about 10, 000 to about l, 000, 00 () g / mol,
- the polyketone may include a repeating unit represented by Formula 2 below.
- the polyketone may be an aliphatic polyketone including ethylene, propylene, isopropylene, or butylene units.
- the polyketone may be more preferably a binary copolymer or a ternary copolymer including two or more repeating units described above.
- the polyketone has a weight average molecular weight of about 10, 000 to about l, 000, 000 g / n) l.
- the polyalkylene carbonate resin composition may further include about 1 to about 30 parts by weight of polylactide based on 100 parts by weight of the polyalkylene carbonate.
- the polyalkylene carbonate resin composition of the present invention may have a mass loss rate due to thermal decomposition at about 25 CTC when the mass loss rate according to the temperature change is about 1 (»or less).
- this invention provides the polyalkylene carbonate resin molded article manufactured with the polyalkylene carbonate resin composition mentioned above. ⁇ Effects of the Invention ⁇
