Description
Technical field
The invention belongs to polymeric material field, relate to a kind of alternately polycarbonate material of structure that is.
Background technology
Carbonic acid gas is the main gas that causes Greenhouse effect, and it is again one of carbon source the abundantest on the earth simultaneously.The chemical fixation of carbonic acid gas is an important research field of Green Chemistry.Wherein, utilizing a main direction of carbonic acid gas is to be raw material and epoxy alkane copolymerization polycarbonate under the effect of catalyzer with it.This superpolymer both can photodegradation, and was also biodegradable; The performance that also has good blocking oxygen and water simultaneously.Therefore, polycarbonate can be used as engineering plastics, biodegradable nonpollution material, disposable medicine and packaging material for food, tackiness agent and matrix material etc.But, problem such as Kai Fa aliphatic polycarbonate material ubiquity second-order transition temperature and intensity is on the low side now, that poly-cyclic carbonate then exists is easily crisp, be difficult to shortcoming such as processing.Chinese patent application number: 03146996.5,02149612.9 and 200510034174.0 successively report prepare matrix material with natural mineral filler, starch or polyvinyl alcohol and aliphatic polycarbonate blending and modifying.People such as Tan change the performance of poly-carbon dioxide plastic in the mode of synthetic fat adoption carbonic ether and poly-cyclic carbonate ester block copolymer (Polymer, 2002,43,4535).Also have scientist's report will be used for carbonic acid gas/propylene oxide/epoxy cyclohexane copolymerization, but what obtain is the polycarbonate material (Macromol.Symp., 2003,195,281) that two second-order transition temperatures are arranged based on the three-element catalytic system of rare earth compounding.And degradability described in the invention is alternately structure polycarbonate material, only have only a second-order transition temperature and one section very narrow heat decomposition temperature, and second-order transition temperature changes with the difference of material 50% heat decomposition temperature with two or more epoxy alkane ratio of using the different of epoxy alkane and participation copolymerization.
At present, the patent report for preparing polycarbonate about carbonic acid gas and epoxy alkane copolymerization is arranged much both at home and abroad.Adopt bicomponent catalyst based on zinc alkyl(s) to obtain molecular weight as U.S. Pat 3585168, US 3900424 and US 3953383 and be higher than 20000 polycarbonate, urethane and polyethers.Day disclosure laid-open patent JP 02142824 and JP 02575199 adopt expensive metalloporphyrin complex catalysis carbonic acid gas and epoxy alkane polycarbonate synthesis, and catalytic efficiency reaches 10

4Gram polymkeric substance/mol catalyst, but polymericular weight has only about 5000, and the reaction times needs more than 10 days.Chinese patent application CN89100701.6 and CN 91109459.8 disclose the bimetallic catalytic system of polymkeric substance load anion binding, also can obtain 10
4The catalytic efficiency of gram polymkeric substance/mol catalyst, but carrier is difficult to separate with the polycarbonate that generates.Chinese patent application CN 98125654.6, CN 00136189.9 and CN 03105023.9 have reported that zinc alkyl(s)/glycerine/rare-earth salts three-element catalytic system is used to prepare molecular weight and is higher than 20000 polycarbonate, and alternating structure is greater than 95%.At U.S. Pat 6133402 and J.Am.Chem.Soc., (2002,124,14284) in, a kind of highly active single-activity point organic zinc catalyzer has been described, obtain molecular weight between 20000 ~ 40000 and be the poly-propylene carbonate of narrow distribution, but also produce 13 ~ 25% cyclic carbonate propylene ester by product synchronously.
Above-mentioned preparation polycarbonate method have low, the long reaction time of catalyst activity mostly, and pressure is higher, needs organic solvent; It is lower to supervene in cyclic carbonate by product or the polymerisate carbonate unit; Problems such as product and catalyst separating difficulty.Recently, the inventor report a kind of under low pressure or middle pressure selectivity catalysis epoxy alkane and carbon dioxide reaction prepare method (Chinese patent application numbers 200410021316.5 and the Angew.Chem.Int.Ed. of the polycarbonate of high molecular, high alternating structure, 2004,43,3574).The present invention is the system that the employed catalyst system of structure polycarbonate material alternately once applied for protecting the same as or similar to us (Chinese patent application number 200410021316.5 and 200510046091.3) at the preparation degradability.
