actually polymer has an internal utility to load css links, i have implemented a javascript function that is using polymer internal css processor,so if you want to add css links at runtime you can use it:

Polymer('my-element', {           
        ready: function () {
           this.importCss("path/myfile.css");
        },
        importCss: function (path) {
             var $shadow = $(this.shadowRoot);
            var $head = $("
");
            var $link = $("");
            $link.attr("href", path);
            $head.append($link);
            var head = $head[0];
            this.copySheetAttributes = Polymer.api.declaration.styles.copySheetAttributes;
            Polymer.api.declaration.styles.convertSheetsToStyles.call(this, head);
            var styles = Polymer.api.declaration.styles.findLoadableStyles(head);
            if (styles.length) {
                var templateUrl = this.baseURI;
                Polymer.styleResolver.loadStyles(styles, templateUrl, function () {
                    var $style = $shadow.find("style");
                    if ($style.length > 0){
                        $shadow.find("style").append($head.find("style").html());
                    }else{
                        $shadow.append($head.html());
                    }
                });
            }
        }
});

Note: this code needs jquery to run
