Composition of a dyeable poly-alpha-olefin and a copolymer. |
摘要 |
<p>A melt kneaded mixture is formed of, by wt, (A) 100 parts of a poly- alpha -olefin (e.g. polypropylene); (B) 1 to 20 parts of an ethylene copolymer having a melt index as defined in JIS-6760 at 190 DEG C of 1 to 1,000 g/10 mins, produced by high pressure continuous polymerization with a free radical catalyst of (a) 40 to 95% of ethylene and (b) 5 to 60% of at least one dialkylaminoalkyl acrylamide comonomer represented by the formula: <CHEM> wherein R1 is H or -CH3; R2 and R3 each is hydrogen or C1-4 alkyl; and n is 2 to 4; and optionally up to 20 wt% of an unsaturated ester (C) 0 to 3 parts of at least one alkali metal salt of a C7-24 organic carboxylic acid (e.g. a stearate); and optionally other additives. This composition can be melt spun into fibers or fabricated into other products, all of which are easily dyed especially with anionic dyes, alone or with other fibers.</p> |
