Abstract: PROBLEM TO BE SOLVED: To improve the high temperature oxidation resistance of a natural rubber which is vulnerable to ultraviolet rays, etc., by coating with a specified polymer. SOLUTION: A structure 10 includes a coat 16 which is formed from a polymer expressed by one of the following formulas: formula I (-CH2 -CXY-)*(-CH2 - CHZ), formula II (-CH2 -CH=CJ-CH2 ), formula III (-CH2 -CHK-O-)*(CH2 -CH2 -O-), where X is methyl group or hydrogen atom; Y is carboxylic acid salt, methyl group, etc.; Z is chlorosulfonyl group or hydrogen atom; J is chlorine atom; K is methyl of chloromethyl group. One or more layers of the polymer are applied at least on the exposed surface 14 of a base layer 12 of natural rubber. The structure 10 is ideal as an engine mount and a gasket.

Abstract: The performance of natural rubber based products, such as engine mounts which are susceptible to degradation caused by heat, oxidation, ozone attack or ultraviolet radiation is significantly improved by coating exposed surfaces of the product with a polymeric material having excellent heat and oxidation resistance properties. By applying such polymeric coatings having high resistance towards oxidation under excessive heat, the C=C bonds of the natural rubber are protected from oxygen and ozone attacks, thereby allowing its strain-crystallization characteristic properties to be retained.

Abstract: The natural rubber base layer of a vehicle suspension device is protected from degradation by heat, oxidation, ozone or UV by having a coating of a polymer of formula (-CH2-CXY-)*(-CH2-CHZ) (I), (-CH2-CH=CJ-CH2*) (II) or (-CH2-CHK-O-)*(-CH2-CH2-O-) (III), where X = Me or H; Y = carboxylate, Me, CN or halogen; Z = chlorosulphonyl or H; J = Cl; and K = Me or chloromethyl.
