DEFINITION

Classification: 525/156

Contacting with a hydrocarbon and an aldehyde or aldehyde derivative as reactants at least one of which is saturated, their condensate or solid polymer thereof:

(under subclass 154) Subject matter wherein the solid polymer from ethylenic reactants only is contacted with a hydrocarbon and an aldehyde or aldehyde derivative as reactants, aldehyde-hydrocarbon condensate or the corresponding solid polymer thereof. The hydrocarbon reactant may not be a solid polymer from ethylenic reactants only (e.g., polyvinyl-naphthalene) which is then further condensed with formaldehyde. However, it can be vinyl naphthalene condensed with formaldehyde and subsequently contacted with a solid polymer derived from ethylenic reactants only.

155, for the reaction of an aldehyde with a solid polymer from ethylenic reactants only subsequently mixed with a chemically dissimilar solid polymer derived from ethylenic reactants only.
