Abstract
A method for damping vibration between two bodies comprising providing a layer of a selected material between opposing surfaces of the bodies wherein said material comprises a cured polymer of a compound having the formula ##STR1## where: R.sub.1 is selected from the group consisting of: (a) an aliphatic hydrocarbon group containing 2 to 10 carbon atoms, and (b) a group having the formula ##STR2## where n=1 to 3 m=0 to 5 R.sub.2 and R.sub.2 ' are each selected from the group consisting of an alkyl group containing 1 to 4 carbon atoms, an unsubstituted aryl group, and a substituted aryl group; and R.sub.3 is: ##STR3##
Claims7
A method for reducing the transmission of vibratory motion between a first body and a second body having opposing surfaces comprising providing a layer of a selected material between said opposing surfaces of said first body and said second body wherein said material comprises a cured polymer of a compound having the formula ##STR18## where:
- R.sub.1 is selected from the group consisting of:
- (a) an aliphatic hydrocarbon group containing 2 to 10 carbon atoms, and
- (b) a group having the formula ##STR19## where n=1 to 3
- m=0 to 5
- R.sub.2 and R.sub.2 ' are each selected from the group consisting of an alkyl group containing 1 to 4 carbon atoms, an unsubstituted aryl group, and a substituted aryl group;
- and R.sub.3 is:
- ##STR20##
