HYDROPHOBIC SUBSTRATE AND ITS MANUFACTURE |
摘要 |
Hydrophobic substrate which can release at least one chemical substance, wherein it comprises a hydrophobic polymer matrix in which are homogeneously distributed inclusions of polymerized compounds of a different type to the said hydrophobic polymer and inclusions of the said substance, the polymerized compound inclusions forming in the said matrix a stable and continuous system in contact with the inclusions of the said substance. Process for the preparation of a hydrophobic substrate able to release a chemical substance, wherein it comprises forming inclusions of polymerized compounds in a hydrophobic polymer powder by grafting onto the latter a monomer of a different type to the said hydrophobic polymer, homogeneously mixing the grafted powder obtained in this way with a powder of the said substance and bringing the mixture into the form of a substrate by hot shaping it. |
