Definitions

• a dye receptive stereoregular polyolefin composition is prepared by using about 2 to 20 percent polyethylene glycol of molecular weight from 100,000 to 5,000,000 meltdispersed in stereoregular polypropylene, polymethylpentens, or polymethylbutene.
• the invention relates to stereoregular polyolefins. More particularly, this invention relates to polymeric compositions having improved afiinity for dyes, said com-positions containing a major amount of stereoregular polyolefins.
• This invention relates to stereoregular polyolefins having increased affinity for dyes and other polar substances
• a matrix of a stereoregular polyolefin taken from the group consisting of polypropylene, polymethylpentene and polymethylbutene said matrix of polyolefin having dispersed therein between about 2 and 20% of a modifying polymer which is hydrophilic, non-soluble in the polyolefin and fusible at a temperature not exceeding the temperature of processing of the polyolefin C. to 350 C.
• said modifying polymer being selected from the group consisting of alkylene oxide polymers having molecular weights between 100,000 and 5,000,000,
• poly N-vinyl pyrrolidone poly N-vinyl morpholine, and t v. poly N-vinyl oxazolidinone.
• ethylene glycol resins of different molecular weight, was prepared and labeled as follows:
• Each of the dried mixtures was prepared in the form of a disc in the following manner.
• the powder of each sample was spread uniformly in a circular shouldered Pyrex glass dish with an inside diameter of 4 inches.
• the dishes were then covered by an inner nesting circular shouldered Pyrex glass dish with a bottom outer separation rib projecting downwardly about 0.05 inch.
• the assembly weighted with a preheated 5 pound weight was then placed in an oven at 250 C. for 6 to minutes. Then the Weight was removed and the assembly was placed in a refrigerator at about 4 C. to cool.
• the assembly dishes were then separated to give a fused disc.
• ASC-Cibalan Brilliant Scarlet RL a neutral dyeing metallized acid dye
• Alkylene oxide polymers of 1000 to 10,000 molecular weight are considered suitable for use in plasticizing or improving the impact resistance of polypropylene. However, if these liquid or waxy substances plasticize polypropylene, they will adversely aifect the desirable properties in films and fibers. As shown, these relatively low molecular weight polyglycols have negligible effect on the dyeability of polypropylene. However, the polyalkylene oxides having molecular Weights of 100,000 to 4,00%- -000 can be used in relatively low percentages with negli gible eifect on desired physical properties to impart a greater degree of dyeability to the polypropylene as indicated by the results above.
• Example 3 In accordance with the general procedure set forth in Example 1, I prepared two separate discs utilizing as modifiers poly N-vinyl oxazolidinone and poly N-vinyl morpholine. The dispersion of each of the homopolymers in each of their respective polypropylene discs was considered fair. Each disc exhibited only a slight increase in opacity over a control. The discs prepared with each of the modifiers was dyed in accordance with the procedure outlined in Example 1. I found that each disc was dyed to a light/ medium shade with DO disperse dyes heretofore described.
• my modifiers with polyolefins are readily available. They may be combined during formation of the polymeric modifier or during actual polymerization of the polyolefin, with or without melting. They may be added to freshly polymerized polyolefin, which is still in solution in a suitable solvent, in the powdered form, or as a solution in a compatible solvent, or merely as a dispersion. They may be added to the polyolefin during precipitation, washing, neutralizing or compounding of the freshly prepared polyolefin prior to drying. This may be accomplished by adding the modifier as a powder or as a solution which is a non-solvent for the polyolefin.
• the modifiers may also be melt mixed during processing or blending of the polymer prior to use in extension of fiber, film, coating or plastic. It may also be added as a liquid or powder to finely ground or micronized polyolefin polymers and then melt dispersed in situ during hot dip or spray coating or during spreading and heat coating operation. They may be incorporated in polyolefin solutions or emulsion and then applied to surfaces with or without heating.
• the level of addition of the modifiers heretofore listed should be between 2 and 20% of the weight of the overall composition. If less than 2% is utilized, significant improvement will not be achieved in dyeability. If an amount greater than 20% is added to the polyolefin, many of the physical properties of the final product, such as fiber or film, are adversely affected. These include loss of strength and a lower resistance to repeated flexing.
• Polyimines have high molecular mobility which apparently gives them some ease of solution in polyolefins. However, there is also a high tendency to sweat out and separate when the combination is made into fiber or film.
• soluble polyvinylpyridines confer little or no dyeability on the polyolefin when dissolved therein. This appears to be the case until the preformed modified polyolefin is post treated with epoxy compounds, concentrated acids, alkylating agents, nitrous oxide gas, and alkylene oxides. However, such post treatments are diflicult, costly and generally impractical.
• hydrophilic polymeric modifiers which may be soluble in either water or an oxygenated solvent but which are not soluble in the polyolefin.
• modifiers which are fusible and can be dispersed in the'polyolefin.
• My hydrophilic modifiers must be fusible with the polyolefin. This is necessary for the formation of a continuous network of modifier throughout the polyolefin in order to permit dye penetration and efficient coordination of the dye and modifier throughout the film or fibre.
• a polymeric composition having improved aflinity for dyes consisting essentially of:
• a matrix of stereoregular polyolefin taken from the group consisting of polypropylene, polymethylpentene, and polymethylbutene;
• said matrix having melt-dispersed therein polyethylene glycol of a molecular weight from 100,000 to 5,000,- 000 in an amount between 2 and 20 percent by Weight of the combination of matrix plus polyethylene glycol as a continuous network throughout the matrix.
