Abstract
The present invention provides a gasket using a polymer composition capable of being cured or crosslinked in the absence or without the use of conventional cure systems. The polymer is formed from olefinically unsaturated monomers. Such polymer includes additional functionality provided by a chelating monomer. Methods of making gaskets or other articles of manufacture either using a beater additions process or a saturation process are also provided.
Claims32
A gasket in which the polymer component thereof contains a polymer formed from olefinically unsaturated monomers wherein additional functionality is provided by a chelating monomer.
A method of making a substrate using a beater additions process comprising the steps of:
- (a) forming a slurry of at least one fiber in water and of a polymer composition comprising at least one olefinically unsaturated monomer and additional functionality provided by a chelating monomer;
- (b) destabilizing the slurry;
- (c) separating out and collecting destabilized solid material to provide a solid mass;
- (d) drying the solid mass;
- (e) forming the solid mass into a substrate;
- and
- (f) curing the polymer composition utilizing a polyvalent metal ion crosslinking agent to crosslink the polymer composition to provide the substrate.
A method of making an article of manufacture by a saturation process comprising the steps of:
- (a) passing a substrate through a dispersion of a polymer composition wherein the polymer composition is formed from at least one olefinically unsaturated monomer and has additional functionality provided by a chelating monomer;
- (b) drying the substrate impregnated with the polymer composition;
- and
- (c) curing the polymer composition utilizing a polyvalent metal ion crosslinking agent to crosslink the composition to form the article of manufacture.
