Abstract
Abstract Adhesive compositions in emulsion form for uniting textiles, wood, metal, leather, etc. comprising a halogenated alpha-monoolefin polymer solution emulsified with resinous polymers of esters of alpha, beta, ethylenically unsaturated monocarboxylic acids and saturated aliphatic alcohols and a curing agent. There may also be included in the compositions certain aldehydecontaining amine precondensates which increase the toughness of the bond.
