Rubbers, rubber compounds, and rubber curing bladders having self release or low adhesion to curing or cured hydrocarbon rubbers. |
摘要 |
<p>Hydrocarbon polymers with grafts of polyethers, polylactones, or polyesters from the reaction of phosgene with glycols having from 1 to 4 carbon atoms are disclosed as having good release properties or low adhesion to hydrocarbon rubber materials. The hydrocarbon backbone polymers include EPDM, hydrogenated polybutadiene, and hydrogenated poly(styrene-butadiene) all said polymers having pendant succinic anhydride groups or brominated p-methylstyrene-isobutylene copolymers. The above-referenced graft copolymers along with butadiene-acrylonitrile rubber or epichlorohydrin polymers or copolymers are described as useful polymers to make self-release curing bladders or sleeves for use in making molded articles such as pneumatic tires.</p> |
