Invention mechanism:

Macromolecular chain in polymer is not closely to pile up completely, always with the presence of gap between macromolecular chain, this Portion void volume is free volume.It penetrates into small molecule inside macromolecule, to have foot in macromolecule or between macromolecule Enough big gaps, so pore size (the i.e. ruler of free volume in the permeability and diffusivity of small molecule and macromolecular structure It is very little) it is related, in a certain range, the size of free volume is bigger, and the permeability of small molecule is higher, and diffusivity is better.Free body Product is divided into empty free volume and slit free volume again, and empty free body has bigger bulk compared with slit free volume, Promotion for the permeability of small molecule, empty free volume are more obvious compared with slit free volume effect.

The size and type of free volume depend primarily on the structure of polymer, and the principal element for influencing polymer architecture is Steric hindrance, side group size, side group structure etc..When position a certain on main polymer chain is replaced by side group, necessarily cause main chain The variation of activity, to change the interaction force of chain and interchain, chain can also occur to change accordingly at a distance from interchain, As a result lead to the variation of cohesive energy and free volume, polarity, size, length of the substituent group on polymer side chain etc. are to strand Rigid, intermolecular interaction so that the fractional free volume of polymer architecture all have a certain impact, therefore, substituent group The effect that difference generates is different, and the permeability and separation performance for often leading to polymer is also different.

For ethylene glycol dihydric alcohol straight chain molecule, the C atom on main chain is arranged in indention one on the other, works as main chain H atom on some upper methylene is by methyl (- CH₃) when replacing, the C atom and main chain C atom in side group be not in same plane Interior, then, four sp3 hybridized orbits on the C of center are Chong Die with the unoccupied orbital on four C atoms around respectively, and formation four is complete Exactly the same σ key is arranged in positive tetrahedron, and four carbon atom is located at four vertex of positive tetrahedron, when three of methyl When hydrogen is further replaced by methyl (tert-butyl) or trimethylsilyl, it is capable of forming a bigger tetrahedral structure, this positive four With respect to the strand that indention arranges, empty free volume significantly increases much the strand of face body arrangement, can be significant Improve the permeability and diffusivity of small molecule；And when the H atom on main chain on some methylene drawn money on credit chain substituent replace when, What is mainly increased is slit free volume, and increase amplitude is smaller, and the permeability and diffusible promotion effect to small molecule are limited, Simultaneously because the rigidity for chain substituent of drawing money on credit is smaller, it is easy to happen entanglement between strand, is unfavorable for the increase of free volume.

The present invention in polyester molecule chain by introducing the hexylene glycol with tert-butyl side group and two with trimethylsilyl side group First alcohol is obviously improved the dyeability and uvioresistant performance of colored terylene hanging belt, the structural formula of the hexylene glycol with tert-butyl side group It is as follows:

In formula, R₂For-H (hexylene glycol with tert-butyl side group is 2,2,5,5- tetramethyl -3,4- hexylene glycol),-CH₂CH₃ (hexylene glycol with tert-butyl side group is 2,2,5,5- tetramethyl -3,4- diethyl -3,4- hexylene glycol) or-C (CH₃)₃(the tertiary fourth of band The hexylene glycol of base side group is 2,2,4,4- tetramethyl -3,4- di-t-butyl -3,4- hexylene glycol)；

In formula, R₁For-CH₂(dihydric alcohol with trimethylsilyl side group is 3- trimethylsilyl -1,2- propylene glycol),-CH (CH₃Dihydric alcohol of)-(with trimethylsilyl side group is 3- trimethylsilyl -3- methyl-1,2- propylene glycol) or-C ((CH₃)₂)-(band three The dihydric alcohol of first silicon substrate side group is 3- trimethylsilyl -3,3- dimethyl -1,2- propylene glycol)；

In hexylene glycol with tert-butyl side group in tert-butyl and dihydric alcohol with trimethylsilyl side group trimethylsilyl presence It can cause the variation of main chain activity, to change the interaction force between chain element, the distance between molecule chain element also can Corresponding change occurs, leads to the increase of the empty free volume of polyester.With short-chain branch substituent group (such as methyl, ethyl group) Compare, tert-butyl and trimethylsilyl occupy biggish spatial position, will be obtained in the mode of strand arrangement it is bigger from By volume；Compared with chain substituent of drawing money on credit, what one side tert-butyl and trimethylsilyl increased is empty free volume, and long-chain branch What substituent group increased is slit free volume, and the rigidity of another aspect tert-butyl and trimethylsilyl is greater than chain substituent of drawing money on credit, and is subtracted The entanglement between strand is lacked, thus tert-butyl and trimethylsilyl have compared with chain substituent is drawn money on credit in the mode that strand arranges There are more free volumes.On the one hand the increase of empty free volume can reduce dye molecule and penetrate into modified poly ester The difficulty in portion improves the dyeability of modified poly ester, reduces dyeing temperature, shortens the time of dyeing, reduces energy consumption, improves and is modified The dye-uptake of polyester (i.e. colored terylene hanging belt)；On the other hand, so that in antistatic finishing agent and uvioresistant finishing agent Molecule reactive group such as-NH₂,-OH ,-COOH can diffuse into fiber gap during heat treatment, improve coloured The antistatic and anti-ultraviolet property of terylene hanging belt.Hexylene glycol with tert-butyl side group of the invention and with trimethylsilyl side group Dihydric alcohol play certain synergistic effect, when can both play a role, to dyeability and uvioresistant performance Raising becomes apparent.

The utility model has the advantages that
