Abstract:
A process for producing a plastisol composition which comprises adding 0.1-5 wt %, based on total plastisol composition, of an adhesion promoter to a plastisol comprising polyvinyl chloride, vinyl chloride copolymer or polyalkylene methacrylate in a plasticizer to form the plastisol composition, wherein the adhesion promoter is a product of:reacting an .alpha.-olefin by radical polymerization with at least one monounsaturated carboxylic acid or monounsaturated carboxylic acid ester or anhydride to form a copolymer; andreacting the copolymer with at least one polyamine having at least one primary amino group to form the adhesion promoter,wherein the adhesion promoter is represented by Formula I, II or III ##STR4## where x=1; y=1-4; n=5-50; R.sub.1 =C.sub.6 -C.sub.22 alkyl radical; R.sub.2 =H or CH.sub.3 ; R.sub.3 =H or C.sub.1 -C.sub.3 alkyl radical; and R.sub.4 is a hydrocarbon radical with 2 to 14 carbon atoms and at least one amino group; or R.sub.3 and R.sub.4 form a piperazine ring with the amide nitrogen atom; ##STR5## wherein x=1; y=1-2; n=5-50; R.sub.1 =C.sub.8 -C.sub.22 alkyl radical; and R.sub.2 is a hydrocarbon radical with 2 to 14 carbon atoms and at least one amine group; ##STR6## wherein x=1; y=1-4; n=5-50; R.sub.1 =C.sub.8 -C.sub.22 alkyl radical; R.sub.2 =H or CH.sub.3 ; A=--OCH.sub.2 CH(OH)--CH.sub.2 --; and R.sub.3 and R.sub.4 are defined as in Formula I.
