Abstract
Carrier comprised of a core, a number of the pores thereof containing a polymer, and thereover a coating.
Claims17
A process for the preparation of carrier comprised of mixing carrier core with a mixture of monomer and initiator, optional chain transfer agent, and optional crosslinking agent;
- polymerizing the monomer by heating thereby resulting in a polymer contained in a number of the carrier pores and on the carrier surface;
- and optionally drying.
An insitu process for the preparation of carrier comprising mixing carrier core with a mixture of monomer and initiator, optional chain transfer agent, and optional crosslinking agent;
- polymerizing the monomer by heating thereby resulting in a polymer, or crosslinked polymer in the carrier pores and on the carrier surface;
- mixing the carrier core containing polymer and monomer mixture inside the pores and on the carrier surface with water;
- completing the polymerization and optionally crosslinking by heating thereby resulting in a polymer, or crosslinked polymer in the carrier pores and on the carrier surface;
- removing the water from the mixture;
- and optionally drying.
