    摘要: A biosensor is prepared having a selective detection system containing a biochemical substance such as an enzyme immobilized on an olefinic-unsaturated, epoxyfunctional polysiloxane. Prior to immobilization of the biochemical substance, the polysiloxane is applied as a layer to a carrier and cross-linked by treatment with high-energy radiation. A biochemical substance is reacted with epoxy groups of the cross-linked polysiloxane. Any non-reacted epoxy groups are reacted with a compound containing an amino group, a carboxyl group or an amino group and a carboxyl group to stabilize. After cross-linking and before reacting of the biochemical substance, the cross-linked polysiloxane can be hydrophilized by reacting some of the epoxy groups with a hydrophilic compound containing a reactive group.

    摘要: A biosensor is prepared having a selective detection system containing a biochemical substance such as an enzyme immobilized by reaction with epoxy groups of an olefinic-unsaturated, epoxyfunctional polyether. Prior to immobilization, the polyether is applied to a carrier and crosslinked by treatment with high-energy radiation or peroxide to form a layer. After reacting the biochemical substance with epoxy groups, non-reacted epoxy groups are reacted with a compound containing an amino group and/or a carboxyl group such as an amino acid. Before immobilizing of the biochemical substance and after crosslinking, the polyether may be hydrophilized by reacting some of the epoxy groups with a hydrophilic compound such as an amino acid.

    摘要: Flame-resistantly formulated, flowable, latently reactive, phenolically curable epoxy-resin moulding compounds for the encapsulation of electronic components containing the following components:an epoxy-resin component obtained from a solvent-free reaction resin mixture of polyepoxy resin and polyisocyanate resin having a molar ratio of the epoxy groups to the isocyanate groups of 1.1 to 4 at a reaction temperature of up to 220.degree. C. in the presence of a reaction accelerator in a concentration of 0.5 to 2.5% and using triphenylphosphine oxide in a concentration of 0.05 to 10%, relative in each case to the reaction resin mixture,a hardener component containing at least two phenolic hydroxyl groups per molecule,inorganic filler,and standard additives.
