Abstract | IR absorption studies of vinyl chloride:vinyl acetate:vinyl alcohol (VC:VAc:VA) terpolymers in the range 4000-400 cm/sup -1/ at temperatures of 298, 323, 348, 373 and 398 K show a broad -OH band at approximately 3460 cm/sup -1/ with a kink at its shoulder on the higher frequency side at approximately 3580 cm/sup -1/. The IR spectra of the films treated at 323 and 348 K show a decrease in the magnitude of the band at approximately 3460 cm/sup -1/ with a slight increase in the magnitude of the band at approximately 3580 cm/sup -1/. The IR spectra of films treated at 373 and 398 K show, besides a shift in the sharp band toward the higher frequency side, an increase in its magnitude, whereas the broad band (at approximately 3460 cm/sup -1/) continues to decrease in magnitude with the rise of temperature. The analysis of these bands and their temperature dependence are reported.< |

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.
