The present invention provides an amine-based polymer, a preparation process thereof and use thereof. The amine-based polymer of the present invention is characterized in that said amine-based polymer contains a polymer main chain, and a structure represented by formula (I) is attached onto the polymer main chain, and said structure is attached to the polymer main chain via an attaching end present in at least one of Group G, Group G' and Group A in the structure, wherein each of the groups is defined as in the description. The amine-based polymer of the present invention is suitably used as a detergent, particularly suitably used as a fuel detergent. The amine-based polymer of the present invention is useful as a fuel detergent, and has an extraordinarily excellent detergency and dispersion properties.

Amine-based polymer, a preparation process thereof and use thereof

The present invention relates to an amino polymer, its main chain is attached via a &#x2014;O&#x2014; group to a structure represented by the following formula (I). The present invention also relates to a process for producing said amino polymer and to its use as fuel oil detergent. Compared with the prior art, the fuel oil detergent of the present invention has the advantages such as a lower manufacturing cost and an improved deposit formation inhibition performance. In formula (I), groups and values are defined as described in the description.

Amine polymer and preparation method and use thereof

Techniques for managing parameterized continuous query templates are provided. In some examples, a continuous query may be generated based at least in part on one or more selections of one or more business logic templates and business event parameters associated with a user. The continuous query may also be configured to retrieve business event data of the user. In some examples, a service provider may receive selection of one or more business logic templates. The service provider may also receive the business event parameters associated with the user. The business event parameters may be received via the selected template. The continuous query may then be generated using the information received via the template.
