COUPLING AGENTS FOR NATURAL FIBER-FILLED POLYOLEFINS AND COMPOSITIONS THEREOF |
摘要 |
<p>The invention is a coupling agent, which is made from a polyolefin composition and is for wetting a cellulosic fiber. The coupling agent desirably includes a polyolefin resin having a melt flow index at 190<SUP>0</SUP>C and 2.16 kg of about 0.5 to 100 (g/10 min). The polyolefin resin is combined with 1.6 to 4.0 weight percent maleic anhydride, and the composition has less than 1,500 ppm of free maleic anhydride. The coupling agent has a yellowness index of 20 to 70. A cellulosic composite can be made from the coupling agent by combining the coupling agent with cellulosic fiber and at least one thermoplastic polymer.</p> |
