Abstract: Aerosol coating compositions contain a conventional propellant such as CHClF2, CCl3F, CCl2F2, CH2Cl2, C2Cl3F3 and C2Cl2F4, together with a coating composition comprising 60% by weight or more of a polymer having a carbon main chain and, spaced along the length of said chain, to which they are attached through ester linkages, pendant vinyl-dioxolane radicals of the formula <FORM:1005205/C4-C5/1> where all but one of the valences of the 4- and 5-carbon atoms are satisfied by atoms or radicals selected from hydrogen, alkyl, aryl, alkaryl, aralkyl, chloroalkyl, fluoroalkyl, alkoxyalkyl, cyano, chloroalkoxyalkyl, fluoroalkoxyalkyl, cyanoalkoxyalkyl, cyanoalkyl, alkenyl, chloroaryl, fluoroaryl, fluorine, chlorine, acylamido and phenylsulphonyl, and R is hydrogen, alkyl, alkenyl, aryl, chlorine, bromine, cyano, acyloxy, chloroalkyl, fluoroalkyl, cyanoalkyl, alkoxy, aryloxy or carbalkoxy; and up to 40% by weight of a thermoplastic resin (see Division C3).ALSO:The invention comprises polymeric compounds with a carbon main chain and, spaced along the length of said chain, to which they are attached through ester linkages, pendant vinyl-dioxolane radicals of the formula <FORM:1005205/C3/1> in which all but one of the valences of the 4-and 5-carbon atoms are satisfied by atoms or radicals selected from hydrogen, alkyl, aryl, alkaryl, aralkyl, chloroalkyl, fluoroalkyl, alkoxyalkyl, cyano, chloroalkoxyalkyl, fluoroalkoxyalkyl, cyanoalkoxyalkyl, cyanoalkyl, alkenyl, chloroaryl, fluoroaryl, fluorine, chlorine, acylamido, and phenylsulphonyl; and R is hydrogen, alkyl, alkenyl, aryl, chlorine, bromine, cyano, acyloxy, chloroalkyl, fluoroalkyl, cyanoalkyl, alkoxy, aryloxy or carbalkoxy; their production by reacting a suitable polymer with a suitable vinyl-dioxolane compound to unite the two by way of an ester linkage, e.g. by transesterification with a hydroxyalkyl-vinyl-dioxolane; and compositions comprising a compatible blend of 60% by weight or more of a polymer as defined above, and up to 40% by weight of a thermoplastic resin.  Suitable polymers for reaction with hydroxyl-containing vinyl-dioxolanes are polymers of acrylic and alkyl-acrylic esters, such as methyl, butyl, hexyl, octyl, decyl and stearyl methacrylates, methyl, ethyl, isobutyl and 2-ethylhexyl acrylates, and dimethyl itaconate and mixtures thereof.  Specified vinyl-dioxolane reactants are 2-vinyl- and 2-isopropenyl-4-hydroxybutyl-1,3-dioxolanes. Suitable thermoplastic resins for use in the compositions of the invention are homopolymers and copolymers of acrylic and a -substituted acrylic esters, such as methyl, ethyl, propyl, isopropyl, isobutyl, amyl, octyl, 2-ethylhexyl and benzyl acrylates, methyl, ethyl, butyl, lauryl, stearyl and butoxyethyl methacrylates, methyl ethacrylate and dimethyl itaconate; acylated cellulose, such as cellulose acetate, acetate butyrate, acetate sorbate, acetate propionate, butyrate, and propionate, and succinylated cellulose acetate butyrate; homopolymers and copolymers of vinyl esters, such as the acetate, propionate, butyrate, caprylate, laurate, palmitate, benzoate and 2-ethylhexoate; copolymers of vinyl or vinylidene chloride with maleic, fumaric or acrylic esters; homopolymers and copolymers of styrene; nitrocellulose; sucrose acetate butyrate; and mixtures thereof.  The compositions may also include liquid vinyl-cyclic acetals, conventional plasticizers, solvents, pigments, extenders, inhibitors and anti-skinning agents.  In an example, a composition containing the polymer and cellulose acetatebutyrate comprises also xylene, hydroxyethyl acetate, methyl ethyl ketone, cobalt butyl phthalate and titanium dioxide.  The compositions of the invention are of use as coating compositions.ALSO:Binders for fibrous webs, e.g. in producing sheets from wood pulp, or for non-woven fibrous webs of natural or synthetic fibres, e.g. cotton, rayon, nylon, polyacrylonitrile, polyethylene terephtholate and polytetrafluoroethylene fibres, or mixtures thereof, consist of compositions containing 60% by weight or more of a polymer having a carbon main chain and, spaced along the length of said chain and attached thereto through ester linkages, pendant vinyl-dioxolane radicals of the formula <FORM:1005205/D1-D2/1> in which all but one of the valances of the 4- and 5-carbon atoms are satisfied by atoms or radicals selected from hydrogen, alkyl, aryl, alkaryl, aralkyl, chloroalkyl, fluoroalkyl, alkoxyalkyP, cyano, chloroalkyoxyalkyl, fluoroalkoxyalkyl, cyanoalkoxyalkyl, cyanoalkyl, alkenyl, chloroaryl, fluoroaryl, fluorine, chlorine, acylamido and phenylsulphonyl, and R is hydrogen, alkyl, alkenyl, aryl, chlorine, bromine, cyano, acyloxy, chloroalkyl, fluoroalkyl, cyanoalkyl, alkoxy, aryloxy or carbalkoxy; and up to 40% by weight of a thermoplastic resin (see Division C3).ALSO:Fabrics and papers are coated with a composition comprising 60% by weight or more of a polymer having a carbon main chain and, spaced along the length of said chain, to which they are attached through ester linkages, pendant vinyl-dioxolane radicals of the formula <FORM:1005205/B1-B2/1> in which all but one of the valences of the 4- and 5-carbon atoms are satisfied by atoms or radicals selected from hydrogen, alkyl, aryl, alkaryl, aralkyl, chloroalkyl, fluoroalkyl, alkoxyalkyl, cyano, chloroalkoxyalkyl, fluoroalkoxyalkyl, cyonoalkoxyalkyl, cyanoalkyl, alkenyl, chloroaryl, fluoroaryl, fluorine, chlorine, acylamido and phenylsulphonyl, and R is hydrogen, alkyl, alkenyl, aryl, chlorine, bromine, cyano, acyloxy, chloroalkyl, fluoroalkyl, cyanoalkyl, alkoxy, aryloxy or carbalkoxy; and up to 40% by weight of a thermoplastic resin (see Division C3).
