MULTIPLE STAGE SEQUENTIALLY PRODUCED THERMOPLASTIC POLYMERS AND FILMS OF SUCH POLYMERS APPLIED TO A SUBSTRATE |
| 摘要 |
<p>Multiple-stage sequentially-produced thermoplastic polymers comprising four specific polymerization stages are particularly useful as films for providing durable surface protective layers to substrates when each of the first and second stages contain 0.1 to 1% by weight of graftlinking monomer. The films are conveniently produced by melt extrusion to a thickness of 0.1 to 50 mils.</p> |
