| Abstract | Interpenetrating polymer network (IPN) based on polyglycidylmethacrylate (PGMA) and acrylamide (AAm) was synthesized using divinylbenzene (DVB) as a crosslinking agent and diphenylselenonium 2, 3, 4, 5-tetraphenylcyclopentadienylide (selenonium ylide) as a new radical initiator. A series of IPNs were prepared by varying the concentrations of AAm, PGMA, DVB and selenonium ylide in dioxan for 90 min at 80 ± 1 °C under an inert atmosphere of nitrogen. Dual phase morphology of the synthesized IPN was revealed by scanning electron microscopy (SEM). The properties like percentage swelling, average molecular weight of network between crosslinks (M$_{c}$) and young’s modulous were direct function of linear polymer [PGMA] and initiator [Ylide] where as inverse function of monomer [AAm] and crosslinker [DVB]. The differential scanning calorimetry (DSC) curve showed glass transition temperature at 127 °C. The synthesized IPN is thermally stable up to 450 °C. FTIR, $^{1}$H NMR and $^{13}$C NMR spectroscopic techniques were used for characterization of polyglycidylmethacrylate and IPN of polyglycidylmethacrylate (PGMA) and acrylamide (AAm). FTIR spectrum confirmed the presence of PGMA, AAm and DVB in the formed IPN by showing their characteristic bands. Similarly, $^{1}$H NMR and $^{13}$C NMR spectrum of the synthesized IPN also exhibit all characteristic peaks of PGMA, AAm and DVB in the formed IPN. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
