    摘要： Functionalized copolymers of isoolefins and conjugated diolefins, methods of preparing said copolymers, and their use as compatibilizers are disclosed. The diolefin monomer units of the co-polymer are modified at the C—C double bond along the backbone of the copolymer to include an oxygen containing functional group such as epoxide, ester or alcohol. The functionalized copolymers improve the wettabilty of a non-hydrophilic surface towards hydrophilic polymer and allows for the formation of homogenous layers of the hydrophilic polymers. In particular, the spreading of a hydrophilic polymer on a non-hydrophilic substrate is facilitated by applying the co-polymers as an interfacial layer between the two incompatible materials. The resulting coated substrates exhibit resistance to protein adsorption and cell growth after grafting. The co-polymers are especially suited in the coating of biomedical devices where a high degree of uniformity of the coated surface is required.

    摘要： The drying time of a piece of wood can be determined by the present apparatus and method, based on a current signal passing through the piece of wood. A set of first and second electrodes of a probe are inserted into the piece of wood which may be travelling on a conveyor. The second electrode has an input for receiving electric power. The first electrode has an output for transmission of the current signal having passed through the piece of wood. The probe is driven toward and away from the piece of wood by a driving mechanism controlled by a control circuit. A measuring circuit is coupled to the outputs of the electrodes. The current signals are measured by the measuring circuit, which determines the drying time of the piece of wood.
