Description
Technical field
Synthesis and application field the present invention relates to graft copolymer, and in particular to a kind of acrylate containing epoxy group
Graft copolymer and its application.
Background technology
Bulking agent refers to using means physically or chemically, incompatible co-mixing system be promoted to be combined together, and then obtain
To the auxiliary agent for stablizing co-mixing system.For polymer blend, due between each component in chemical constitution, polarity, molecular weight
（Viscosity）It causes to be separated with the difference in crystallinity, leads to the poor performance of polymer blend.Therefore, bulking agent is high level
The foundation stone of blending and modifying product.Particularly in current raw material and modified materials market, the factory formula of enterprise and technological process
Come into the open mostly, transparence, the addition of bulking agent then becomes the key point of material modification manufacturer and rival's differentiation.
For the polymer blend containing reactive group in system, usually using reactive compatibilizer.Common reaction
Type bulking agent is mostly Graft copolymer, such as PP grafted maleic anhydrides（102924661 B, CN 101519477 of Chinese patent CN
B）, styrene-grafted maleic anhydride（102993350 B of Chinese patent CN）, ABS grafted maleic anhydrides etc..This kind of bulking agent is more
The method squeezed out using frit reaction, the grafting functional group on polymer molecular chain obtain graft reaction type bulking agent, raw
Production. art is simpler.Although this kind of bulking agent can solve the problems, such as polymer blend compatibility to a certain extent, due to work
Skill limits, and single varieties, grafting rate is low, mostly acid anhydrides type bulking agent.Compared with anhydride bulking agent, epoxies bulking agent and carboxylic
Base and hydroxyl have higher reactivity, have better compatibilization effect in polyester alloy.It is connect to obtain epoxy group
The bulking agent of branch, 102492101 A of Chinese patent CN disclose a kind of by glycidyl methacrylate（GMA）It is grafted to
Method on ABS resin using the technique of fusion-grafting, can obtain the graft with epoxy group, although method is simple,
Side reaction is more, and reaction is difficult to control, and epoxy grafting rate highest only has 0.67%.Additive amount is larger in actual use, increase-volume efficiency
Low, therefore, the bulking agent that fusion-grafting method obtains tends not to meet actual demand.
In order to realize effective control to bulking agent structure and grafting rate, patent of invention of the E.I.Du Pont Company early in 1973
Ethylene-butyl acrylate-glycidyl methacrylate is just prepared using the method for copolymerization in US3723570（PTW）Ternary
Copolymer compatibilizing agent.On this basis, 101851321 B of Chinese patent CN use the technique of suspension polymerisation, are prepared for ternary and are total to
Polymers bulking agent styrene-acrylonitrile-glycidyl methacrylate（SAG）Bulking agent, can be with control ring by this method
The content of oxygen groups, obtains the bulking agent product of high grafting rate, and the grafting rate of epoxy group can be up to 10%.Due in system
Containing styrene and acrylonitrile unit, therefore the bulking agent is especially suitable for ABS class alloy systems.Compared with other bulking agents,
The bulking agent can effectively improve ABS and polyethylene terephthalate（PET）The compatibility of alloy（CN 102181122 A）
With makrolon and the thermal stability of ABS alloy（CN 104877326 A）.
The structure of more than bulking agent is mostly line style bulking agent, in practical applications, the reactive group content of high grafting rate
Can improve the compatibility with a wherein phase, but the winding of molecule interchain can only be often relied on another phase, active force compared with
It is weak.And by adjusting bulking agent structure, while reactive group grafting rate is ensured, introduced and another phase on its main chain
The polymer segment of thermodynamic compatibility can effectively improve winding and the two alternate compatibilities of molecule interchain.Chinese patent
103421154 A of CN disclose a kind of comb-grafted copolymer containing reactive group and its preparation method and application.The patent
By introducing polyacrylate homopolymers segment on polymer lateral chain, using free-radical polymerized method, high grafting is obtained
The comb-shaped polymer of rate.Compared with the bulking agent of commercialization, which can effectively improve the modulus of PET/ABS alloys, fracture
Elongation, yield strength and tensile strength etc. have the better increase-volume efficiency of higher than the line style bulking agent of identical grafting rate（WY
Dong, HT Wang, MF He, et al. Synthesis of Reactive Comb Polymers and Their
Applications as a Highly Efficient Compatibilizer in Immiscible Polymer
Blends [J]. Industrial & Engineering Chemistry Research, 2015, 54: 2081-
2089）.The comb-grafted copolymer that the patent of invention obtains also has chain extension effect.Nevertheless, bulking agent side in the patent
The polymer segment of chain is mainly the homopolymer of methyl acrylic ester or acrylic ester monomer, in practical applications side chain with
Another phase tends not to compatible well.Homopolymer single on bulking agent side chain has specific polarity and solubility simultaneously
Parameter also limits its application to a certain extent.
