DEFINITION

Classification: 525/153

With saturated ketone reactant or polymer thereof; or with solid copolymer derived from at least one ketone reactant wherein at least one of the reactants forming the solid copolymer is saturated; or with specified polymer-forming ingredients wherein at least one of the necessary ingredients is a ketone or with a reaction product thereof; or with a specified intermediate condensation product containing a ketone group:

(under subclass 55) Subject matter wherein, in addition to the solid polymer derived from ethylenic reactants only, there is additionally present (a) a saturated ketone reactant or a polymer thereof, or (b) a solid copolymer derived from a ketone-containing reactant wherein at least one of the reactants forming the solid copolymer is saturated, or (c)

specified polymer-forming ingredients wherein at least one of the necessary polymer-forming ingredients contains a ketone group and at least one of the necessary polymer-forming ingredients is saturated or a reaction product thereof, or (d) a specified intermediate condensation product which contains a ketone group.
