MELT-PROCESSIBLE VINYL FLUORIDE INTERPOLYMERS OF LOW CRYSTALLINITY |
| 摘要 |
In a first aspect, a melt-processible interpolymer consists essentially of units derived from vinyl fluoride and at least two highly fluorinated monomers, at least one of the highly fluorinated monomers introducing into the polymer a side chain of at least one carbon atom. The interpolymer has a melt flow rate in a range of from about 2 to about 250 grams per 10 minutes at a temperature of 280° C.;In a second aspect, an emulsion polymerization process for preparing a melt-processible interpolymer includes polymerizing vinyl fluoride and at least two highly fluorinated monomers in water with a water-soluble free-radical initiator at a temperature in the range of from about 60 to about 100° C. and a pressure in the range of from about 1 to about 12 MPa. |

1. A melt-processible interpolymer consisting essentially of units derived from vinyl fluoride and at least two highly fluorinated monomers, at least one of the highly fluorinated monomers introducing into the polymer a side chain of at least one carbon atom, wherein the interpolymer has a melt flow rate in a range of from about 2 to about 250 grams per 10 minutes at a temperature of 280° C. |
