The advantage that can not obtain before the invention provides.For example, the invention provides moulding compound, although it contains different m-phthalic acid group and ethylene glycol groups derived from the PET that is used to prepare PBT on the structure, function is with equally matched based on those of pure PBT.Because moulding compound does not need the PBT of conventional preparation,, and the needs of in refuse landfill, handling PET or handling it by burning have been reduced thus so the present invention has increased and uses the demand of PET refuse by producing value-added PBT composition.Said composition also demonstrates the character of improvement because having used multifunctional carboxyl-reactive material.

In addition, the preparation method of PBT random copolymers that is used for the PET-deutero-modification of the present composition can advantageously significantly reduce the release and the solid waste of carbonic acid gas.Owing to the PBT random copolymers of the PET-deutero-polyester modification for preparing by method of the present invention is made by refuse PET rather than monomer, so this method has significantly reduced amount and solid waste that carbonic acid gas discharges.Cause the minimizing (or saving of crude oil) of carbon refuse, this is because not using to constitute prepares the dimethyl terephthalate (DMT) of polyester or the carbon of terephthalic acid usually, the substitute is the PET component, for example polyester waste.The method that is prepared DMT or TPA by crude oil is the height energy-intensive, therefore can discharge CO in a large number when the burning Nonrenewable energy resources ₂In atmosphere.By not using DMT or TPA to prepare PET deutero-PBT, the release of carbonic acid gas has obtained saving.In one embodiment, compare with the method that is prepared pure PBT homopolymer by monomer, for the PBT of the every kilogram of PET-deutero-modification for preparing with present method, the method for the PBT of preparation PET-deutero-modification can be eliminated 1kgCO at least ₂Discharge.In another embodiment, compare with the method that is prepared pure PBT homopolymer by monomer, for the PBT of the every kilogram of PET-deutero-modification for preparing with present method, the method for the PBT of preparation PET-deutero-modification can be eliminated 1kg～1.5kg, perhaps more CO ₂Discharge.In addition, when reclaiming the ethylene glycol by product and being used for replacing common ethylene glycol in the mill, but the release of conserve energy/minimizing carbonic acid gas.

In addition, the raw material that derives from biomass derived when the BDO source is for example during Succinic Acid, because the former thereby further saving that increases carbonic acid gas of two aspects.Biologically-derived Succinic Acid is by sugar or derived from other biologically-derived hydrocarbon preparation of big gas carbon rather than fossil oil carbon source, reduce thus based on the BDO derived polymers of Succinic Acid in authigenic material source to the influence of environment.In addition, fermentation produces Succinic Acid needs carbonic acid gas as input, further causes carbonic acid gas to reduce thus.

Advantageously, the moulding compound that contains the polybutylene terephthalate random copolymers of modification can have the CO of reduction ₂Discharge index (emissions index).The CO of Ding Yi reduction in this application ₂The release index is meant, and uses the CO in kg that produces when preparing composition derived from monomeric polybutylene terephthalate ₂Amount compare the CO that when preparation 1kg contains the composition of polybutylene terephthalate random copolymers of modification, is saved in kg ₂Amount.In general, the CO of the common reduction of composition of the present invention ₂Discharge index greater than about 0.06kg, and can be 0.06kg～2.25kg.

The basis of this feature is discussed below.Prepare in the usual way process of PBT of pure monomer derived and the CO that produces in the procedure of the polybutylene terephthalate random copolymers of preparation 1kg modification ₂The difference of amount can be 1.3kg～2.5kg, be 1.7kg～2.2kg perhaps preferablyly.Should be noted that this difference is based on beginning whole process to monomer to PBT from crude oil with respect to beginning from refuse PET to oligopolymer calculating to the PBT of modification again.In other words, compare with the method for preparing the pure PBT of 1kg from crude oil, the method for the polybutylene terephthalate random copolymers of preparation 1kg modification produces 1.3～2.5 kilograms of CO less ₂(it has the PBT random copolymers of modification, and the amount of existence is the CO of 5～90wt.%) reduction in order to determine composition of the present invention ₂Discharge the exponential scope, CO ₂Reducing index can followingly calculate: the upper limit amount that the lower limit amount in per-cent that is present in the polybutylene terephthalate in the composition multiply by 1.3 (0.05x1.3=0.065) and polybutylene terephthalate multiply by 2.5 (0.90x 2.5=2.25).

Can be by using matter and energy EQUILIBRIUM CALCULATION FOR PROCESS (the known calculating of field of chemical engineering), and will prepare the amount of the used energy of the PBT random copolymers of modification from PET and make comparisons with the amount for preparing the used energy of PBT from terephthalic acid, derive and confirm these results.
