Technical field
The invention belongs to terminator production technical fields, and in particular, to a kind of environment-friendly long-life PVC terminator and its preparation
Method.
Background technique
Terminator (English name terminator) also known as polymerization stabilizer (polymerization stabilizer)；
Chain terminating agent (chain terminator): polymerization inhibitor (retarder).It is the use of polymer chemistry chain polymerization reaction process
Agent can terminate the substance that polymerization reaction continues in chain polymerization reaction.These substances can be with initiation free radical and growth
Radical reaction makes them lose activity, so that the growth of terminating chain, stops polymerization reaction and continue, effect is freely
The terminator of base.Polymerization reaction is terminated in due course, can get the high-quality polymeric articles of molecular weight uniform, molecular structure stabilized.
In the production, storage, transport of some polymerized monomers, to prevent the reaction of monomer auto-polymerization from occurring, need to be added terminator, such as
The monomers such as styrene, methacrylic acid, working is as stabilizer, polymerization inhibitor.
It selects to be considered as following factor when terminator:
(1) terminator selection will consider adaptability, such as temperature, acid-base property etc. to application conditions.Efficiency wants high, is added a small amount of
(ppm concentration) can be such that polymerization reaction terminates, and still work in the subsequent processes such as monomer removal；
(2) the not stability of shadow polymerization process and the physicochemical properties of polymer, do not make polymer discoloration, have taste；
(3) soluble easily in water, and can store as an aqueous solution；
(4) it after polymer discharge, is easily eliminated from reactor, inhibition will not be generated to next group polymerization reaction；
(5) cheap, non-toxic or low-toxic, use is safe.
For terminator, it is derivative that the Chinese patent of Publication No. CN103288988B discloses a kind of styrol bisphenol-A
Preparation method of the object as polyvinyl chloride terminator, belongs to synthetic material auxiliary agent technical field.It is produced to improve antioxidant bisphenol-A
It is derivative to prepare styrol bisphenol-A with bisphenol-A and styrene progress catalytic alkylation reaction for the intermiscibility of product in the polymer
Object is used for polyvinyl chloride (PVC) terminator.More particularly to styrol bisphenol-a derivative and zinc Isoocatanoate and a kind of liquid sulfur
Ethers antioxidant and a kind of bisphenolmonoacryates compound and liquefied blender and a kind of decolorising agent are compound, and liquid is made
Terminator product.Reacted with bisphenol-A with alkylated styrene and styrol bisphenol-a derivative be made, have simple production process,
Raw material is easy to get, product use cost is low, is convenient for the characteristics of industrial application, and the terminator is with nontoxic, environmentally friendly
