What glue to use for separated seam?

My Patagonia jacket is over 15 years old and is no longer made. The seams have separated at the underarms and along the sleeves. I am not going to use duct tape so please don’t suggest it. I need to know what glue I can use to seal the seams without damaging the fabric. This is the best lightweight jacket Patagonia ever made. It is not clingy and has no nylon. It is 100% polyester and can truly be worn in many light weather conditions. I love this jacket - please help!
