| Abstract | The scrap rubber powder (SRP) could be compression moulded to form elastomer via in situ interfacial reactions. In this study, SRP/NR (85/15) blends with good performance could be prepared by incorporating a little amount (lower than 5 phr of SRP and NR) of m-phenyl bismaleimide (BMI) in the compositions. The mechanical properties and the interface of SRP/NR (85/15, w/w) blends (base blend) were investigated. The results showed that the processing temperature, time, and BMI content have significant effects on the mechanical properties of the blends. The optimum BMI content and processing condition were determined as 5 wt.% and 180 $^{○}$C/10 min. The mechanical properties, especially the elongation at break, of the elastomers could be improved further by ultraviolet (UV) exposure. With UV exposure, the tensile strength, elongation at break and tear strength of the modified base blend were determined as 10.4 MPa, 260% and 24 KN/m respectively. The FTIR results indicated that the BMI could be grafted onto the SRP surface under UV exposure. The composition with UV exposure had more uniform dispersion of the BMI and improved interfacial adhesion. The glass transition temperature (T$_{g}$) of the blends was increased by increasing the processing temperature, processing time or the introduction of UV exposure. |

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.
