Abstract
A process for producing a fiber reinforced polymer sheet by paper-making technology starting from an aqueous dispersion of thermoplastic polymer particles and fibers having a minimum length of 2.0 mm, characterized in that the polymer is an alternating copolymer of ethylene and carbon monoxide with an average weight molecular weight of at least 6000 and the fibers are used in an amount of from 5 to 450 pbw per 100 pbw of polymer.
Claims8
A process for producing a fiber reinforced polymer sheet by paper-making technology comprising:
- (a) mixing particles of a thermoplastic polyketone polymer and water to form an aqueous dispersion of thermoplastic polymer particles and fibers having a minimum length of 2.0 mm, said polyketone polymer being an alternating copolymer of carbon monoxide and an olefinically unsaturated compound with an average molecular weight of at lest 2000 and having recurring units [A--CO] where A represents the olefinicially unsaturated compound polymerized therein;
- (b) passing said aqueous dispersion onto a filter;
- and
- (c) draining the water from the dispersion, characterized in that the fibers are used in an amount of from 5 to 450 pbw per 100 pbw of polymer.
