I would suggest you to pursue Mechanical from AIT Pune, which has certainly much higher career scope and placement prospects than Polymer at ICT Mumbai. Being located near Industrial and Manufacturing Hubs of Pune and Pimpri Chinchwad, provide huge scope and impetus to training and placements besides providing effective engineering education.

On the other hand, ICT Mumbai is perhaps the best State Engineering College with VJTI and COEP, after Central Institutes VNIT and IITB. Incase you are interested in pursuing a MS/PhD or Research in future, in that case you may prefer Polymer at ICT Mumbai over AIT Pune Mechanical, otherwise, going by Placements and future career and industry prospects, AIT Pune is a much better option.
