Abstract
The invention relates to emulsions of organic peroxides comprising organic peroxide, water, antifreeze, optionally nonionic surface-active agent, and optionally protective colloid which have a low viscosity and excellent stability over time, as well as to the use of such emulsions in the polymerization of ethylenically unsaturated monomers, particularly vinyl chloride.
Description
The present invention relates to comprise the emulsion of at least a organo-peroxide, this emulsion is suitable for ethylenically unsaturated monomer, the particularly suspension of vinyl chloride monomer or emulsion (being total to) polymerization.
The suspension of ethylenically unsaturated monomer or emulsion (being total to) polymeric is realized generally being to use protective colloid and/or tensio-active agent and as the free radical polymerization initiator of polymerization starter, as organic superoxide, is formed the polymkeric substance of desired size distribution.In addition, when making vinyl chloride (be total to) polymkeric substance, the sector is being sought the improvement of productivity and is being reduced pollution to environment, for example by reducing the refuse amount that the reactor dirt generates in forming and the loss of minimizing unreacted monomer.As a result, use the large-scale polymerization unit of automatization day by day and the design of equipment to make the carrying out of whole polymerization process not enter air (so-called enclosed reaction vessel technology).
Be applicable to the polymerization initiator composition of these processes increasing be the organo-peroxide of water-emulsive organo-peroxide rather than solvent cut.This development mainly is because aqueous peroxide emulsions is easy to handle and safety.The various aqueous peroxide emulsions of this purposes has been proposed recently.For example in patent application JP Hei56-139509, the polyvinyl acetate (PVA) that contains organic superoxide, tensio-active agent, protective colloid such as partial hydrolysis and the aqueous organic peroxide emulsions of water-soluble alcohol are disclosed.Similarly, in patent application JP Hei61-130315, disclose and contain organic superoxide, nonionogenic tenside, mean polymerisation degree and be no more than 600 and the polyvinyl acetate (PVA) of at least 60% mole of degree of hydrolysis and the organo-peroxide aqueous emulsion of water-soluble alcohol.In suspension (being total to) polymerization that described aqueous peroxide emulsions contains the protective colloid that has high stability in water and is used in vinylchlorid.(being total to) polymkeric substance and (being total to) polymerization noun used in this piece document relate to homopolymer, all kinds multipolymer such as segmented copolymer, terpolymer, alternating copolymer, random copolymers etc. and relate to the polymerization process of making these polymkeric substance.
Should also be noted that and disclose the polyvinyl acetate (PVA) that comprises organo-peroxide, degree of hydrolysis 5-70% and the emulsion of water-soluble alcohol among the patent application JP Hei62-086005.
Yet traditional emulsion has various shortcomings.Specifically, the emulsion that obtains in JPA-56-139509 has high viscosity.Particularly under higher peroxide concentrations, generate the high viscosity emulsion, in producing, transport and using, be difficult for handling.In addition, reduction is used as the dispersant dosage of emulsifying agent to reduce viscosity, then can reduce stability in storage widely.
Organic peroxide emulsions with JP-A-61-130315 and the described method manufacturing of JP-A-62-086005 has acceptable viscosity, but its stability in storage deficiency, the actual inconvenience of using.In addition, although promptly demonstrate acceptable low viscosity after some traditional organic peroxide emulsions compound production, viscosity can sharply increase in time in storage, when for example storing and/or storing for a long time under the low temperature of about-20 ℃ of temperature.When the emulsive organo-peroxide has highly water-soluble and low-gravity, can observe this undesirable phenomenon.
Notice that JP-A-58-134103 discloses a kind of suspension polymerization of VC method, wherein organic peroxide emulsions is used for starting polymerization.For making PVC have high-insulation, the tensio-active agent that the preparation organic peroxide emulsions is used is selected from the non-ionic surface emulsifying agent of no poly suboxygen ethyl.
In addition, US 5278262 discloses a kind of polymerization unit and has utilized microsuspension or emulsion polymerization to prepare the method for paste PVC.Organic peroxide evocating agent be with in the solvent or VCM in emulsion form add.

By the used polymerization process of the inventor, estimate the providing below of emulsion of aqueous peroxide of the present invention.But aqueous peroxide emulsions can be used in any traditional vinyl chloride monomer (being total to) polymeric method.Preferred said traditional polymerization is that vinyl chloride monomer suspends or emulsion (being total to) polymerization, because in this way use emulsion of the present invention to find to cause reactor fouling few.Because reactor fouling is few, do not need often to open, this has just reduced monomer and has escaped into the amount of environment, and has reduced the workman and be exposed to this monomeric chance.Be noted that PVA is generally as protective colloid, although in emulsion (being total to) polymerization, generally use tensio-active agent to be used as dispersing auxiliary in (being total to) polymerization that suspends.
Aqueous peroxide emulsions of the present invention is that the utmost point is suitable for making and has proportion and be lower than 1 and the composition of the organo-peroxide of highly water-soluble.Highly water-soluble is meant the water-soluble greater than 100ppm weight of superoxide, preferably is higher than 500ppm, more preferably is higher than 1000ppm.The good stability of these emulsions is not even long-time the storage as more than 6 months, can be observed yet and be separated.In addition, this emulsion has low viscosity, promptly is lower than for 500 milli handkerchief seconds under-10 ℃, make, transportation and use in handle easily.And, the few benefit of aggregation container fouling is arranged.Therefore, this emulsion is specially adapted to the especially closed reactor polymerization of the automatization of vinylchlorid of ethylenically unsaturated monomer.
The following examples and comparative example illustrate the present invention.
Embodiment 1-7, Comparative Examples A-D
