Description
Technical field
The present invention relates to contain can be by renewable resources carbohydrate deutero-polycarbonate part, excellent heat resistance and preparation method thereof.
Background technology
Usually polycarbonate adopts the feedstock production that is obtained by petroleum resources, still because the exhaustion of worry petroleum resources needs to adopt the method by the feedstock production polycarbonate of renewable resourcess such as plant acquisition.
In addition, known following formula (3)
Shown ether glycol can be at an easy rate by renewable resources, for example preparation such as carbohydrate and starch, and it has 3 kinds of steric isomers, is specially following formula (5)
Shown by 1,4:3,6-two dehydration-D-Sorbitol Powders (in this manual hereinafter referred to as " Isosorbide "), following formula (6)
Shown by 1,4:3,6-two dehydration-D-mannitols (in this manual hereinafter referred to as " different mannide "), following formula (7)
Shown by 1,4:3,6-two dehydration-L-iditol (in this manual hereinafter referred to as " different iditol ").
Isosorbide, different mannide, different iditol can be made by D-glucose, D-seminose, L-idose respectively.For example for the situation of Isosorbide, can be by after making the D-glucose hydrogenation, dewater and make with acid catalyst.
All the time, in above-mentioned ether glycol, particularly to being that the center is built into polycarbonate as monomer and has carried out (for example studying with the Isosorbide, German patent application discloses No. 2938464, " Journal fuerpraktische Chemie ", 1992, the 334th volume, the 298th～310 page, " Macromolecules ", 1996, the 29th volume, the 8077th～8082 page, " Journal of Applied Polymer Science ", 2002, the 86th volume, the 872nd～880 page).
But there is the problem of forming process difficulty in the polycarbonate that is made by Isosorbide because its rigid structure makes second-order transition temperature and melt viscosity become very high.
In addition, also reported prepare Copolycarbonate by Isosorbide and various bis-phenol method (for example, the spy opens clear 56-110723 communique, " Macromolecular Chemistry and Physics ", 1997, the 198th volume, the 2197th～2210 page, " Journal of Polymer Science:Part A ", 1997, the 35th volume, the 1611st～1619 page, " Journal of Polymer Science:Part A ", 1999, the 37th volume, the 1125th～1133 page), but have the problem of these raw material sources in oil.
On the other hand, for by aliphatic diol deutero-polycarbonate, by ethylene glycol, 1, the 4-butyleneglycol, 1, the 5-pentanediol, 1, the second-order transition temperature of deutero-polycarbonate such as 6-hexylene glycol is respectively 0～5 ℃,-35 ℃,-41 ℃,-50 ℃ (for example, " Journal of Polymer Science:Polymer Letters Edition ", 1980, the 18th volume, the 599th～602 page, " Macromolecular Chemistry and Physics ", 1998, the 199th volume, the 97th～102 page, " polycarbonate resin handbook, this single-minded volume, Nikkan Kogyo Shimbun, 1992, the 21st page).
As these aliphatic diols, also can utilize renewable resources, but by aliphatic diol deutero-polycarbonate because its softish structure, at room temperature be oily or low-melting solid usually, exist to lack stable on heating shortcoming, do not report the multipolymer that second-order transition temperature is higher.
In addition, about the report of the Copolycarbonate of Isosorbide and aliphatic diol less, as one of them, reported 1, the 4-butyleneglycol, 1, the 6-hexylene glycol, 1, the 8-ethohexadiol, the Copolycarbonate of aliphatic diol such as decamethylene-glycol and Isosorbide (field, ridge etc. for example, MEXT's expenditure of scientific research subsidy specific area research (B) " environment underload polymer " is based on the 7th public theory collected works lecture of the structure summary collection by the lasting section bar material system of renewable resources production environment underload plastics, 2002, the 26th～29 page, " Journalof Polymer Science:Part A ", 2003 years, the 41st volume, the 2312nd～2321 page).
These polycarbonate are segmented copolymer or random copolymers, and glass transition point descends along with the growth of separately aliphatic chain, is observed 65 ℃ or 59 ℃, 26 ℃ or 20 ℃, and 12 ℃ or 23 ℃ ,-1 ℃ or 7 ℃, so lack thermotolerance.
In addition, the application basis after the applying date disclosed spy open and put down in writing the thermoplastic molding materials that contains the polycarbonate compound that makes by Isosorbide in the 2003-292603 communique, even but its second-order transition temperature is compared enough height with room temperature, but also need further to improve thermotolerance.
