Description
Technical field
The present invention relates to the polymeric amide technical field, particularly, relate to a kind of nylon copolymer and preparation method thereof.
Background technology
Polymeric amide (PA, be commonly called as nylon) have that good mechanical property, oilness and rub resistance are good, fusing point is high, to advantages such as stable, heat-resisting good, the electrical insulating property of chemical reagent (except strong acid, highly basic) and weathering resistancies, be the engineering plastics that output is maximum in the world, purposes is the widest, be widely used in the fields such as automotive industry, electronic apparatus industry, transportation, machine industry, electric wire communications industry, packing and articles for daily use.Yet also there are under dry state or low temperature the shortcomings such as shock strength is low, opaque, poorly soluble in polymeric amide, this has limited its application.
For this reason, people wish polymeric amide is carried out to modification, improve its physical strength, elasticity, plasticity, flexibility, second-order transition temperature, degree of plasticification, fusing point, resistance toheat, properties of transparency, solubility property, dyeing behavior, surface property, water absorbing properties, dimensional stability etc.Wherein, the copolycondensation method has the characteristics such as technique is simple, effect is good, and development rapidly.According to the difference of copolymer structure, modified technique can be divided into: random copolymerization, block/short block copolymerization, graft copolymerization and alternating copolymerization etc.
The domestic and international most study of wherein random copolymerization technique, the monomer of serving as reasons with different functional groups synthesizes by different methods, but different functional groups and same functional group are often different in the reactive behavior of different polymerizing conditions, thereby cause the difference of speed of reaction and product structure.The performance of random copolymers is the neutralization of each component property to a certain extent, thereby makes performance variation not, can not meet the needs of more extensive occasion.On the contrary, block copolymerization can be adjusted by composition, length, block number and the aggregation structure of regulating each segment the performance of product, to meet the requirement of different occasions, thus block be widely used in polyamide modified, especially high performance polymeric amide synthetic.
Preparation block copolymerization acid amide mainly contains three operational paths: lactan or amino acid whose multistep processes active anionic polymerization; The acid amides permutoid reaction of equal polycondensation prepolymer melting mixing; The solid state condensation of equal polycondensation prepolymer, but all there is defect in these three routes.Adopt anionoid polymerization and acid amides permutoid reaction, product composition changes with level of response, be mainly in the early stage homopolymer, to generate a certain amount of block polymer thereafter, to become the mixture formed by random copolymers, segmented copolymer and homopolymer when level of response is high again, therefore by these methods, be difficult to synthesize segmented copolymer completely.Though adopt solid state condensation to improve to some extent to above problem, have the defect such as speed of response is slow, plant factor is low, the crystallization aftertreatment trouble of product and be difficult to carry out suitability for industrialized production.In addition, while adopting the synthetic block copolyamide of anionoid polymerization, the selection of activation system is very important to improving block content.Marek etc. take contain N-acidylate hexanamide terminal group between bit-type low molecular weight aromatic polymeric amide be that activator causes the polymerization of hexanolactam, finally obtains the product that segmented copolymer content is higher.Stehlicek etc. have studied the PA6-b-12 copolymerization system; low-molecular-weight nylon 12 and N-benzoyl-laurolactam are carried out to acidolysis reaction and make activator; cause the polymerization of hexanolactam, in its product, the content of segmented copolymer can be up to 88.9%-98% again.
In block copolyamide, the phase structure of each component is large to the performance impact of goods, and it is a lot of to affect the factor of phase structure, as chemical constitution, reaction conditions and complete processing etc.Elllis etc. study discovery, and the PA46/PA66 blend system exists macroface to separate, even think that the close PA of structure is also incompatible.But, while in above-mentioned system, having a small amount of segmented copolymer, consistency is improved greatly.During the block copolymer systems of the research PA6 such as Shu and aromatic series polyamide, find: no matter be that micron-scale phase separation all appears in diblock system or many block copolymer systems, and form new crystal formation in many block copolymer systems.During the melt blending system of the research PA66 such as Ahn and semi-aromatic (being total to) polymeric amide, find: with adopted aliphatic dibasic acid, form different, complicated variation appears in consistency, and the Binary-phase Interaction Model of experimental result and ElliS is compared, find to exist certain deviation between the two.
Segment copolymerization method is mainly used in improving impact-resistance and high performance material.Raevskaya etc. make the PA6-b-12 polymkeric substance by melt blending, flexible due to PA12, and degree of crystallinity is low, in system, is amorphous phase, has served as soft component, thereby has improved erosion-resisting characteristics.The acquisition of high performance material is mainly to realize by introducing the aromatic polyamide chain link, and this is also the synthetic high molecular important means of PA class liquid crystal type.Scheetz etc. have studied PA46 and PA6,66,610 etc. segmented copolymer, have not only improved the impact-resistance of material, and have solved the unmanageable difficulty of PA46.During the block copolymer system of research nylon such as Wang 6 and aromatic series PA, find: have Tg and the Tm of the material of block all to increase, thermostability improves, mechanical property strengthens, and many block copolymer systems are better than the improvement effect of three block copolymer systems, in many block copolymer systems, also may form new crystal formation.Malcolm etc. select the PA of fatty six-ring and phenyl ring, have synthesized preferably block copolymerization acid amide liquid crystal material of processibility.
