Claims
- 1. A plastisol composition comprising (a) a copolymer resin of a normal .alpha.-olefin and maleic anhydride (1:1 mole ratio) having a particle size in the range from about 0.1 to about 1500 microns and having the structure ##STR8## wherein B is a member of the group consisting of ##STR9## and ##STR10## R is H or C.sub.x H.sub.2x+1, x is 1 to 16 and n is 2-300, and (b) 65-600 parts/100 parts copolymer of a thiol plasticizer having the formula
- R'--(SH).sub.x
- wherein x is at least one and R' is an organic moiety.
- 2. A container closure comprising a cap having deposited therein a resinous mass functioning as a gasket to seal the container when the closure is in sealing relationship with the container, said resinous mass comprising a fluxed plastisol of a composition comprising (a) a copolymer resin of a normal .alpha.-olefin and maleic anhydride (1:1 mole ratio) having a particle size in the range from about 0.1 to about 1500 microns and having the structure ##STR11## wherein B is a member of the group consisting of ##STR12## R is H or C.sub.x H.sub.2x+1, x is 1 to 16 and n is 2-300, and (b) 65-600 parts/100 parts copolymer of a thiol plasticizer having the formula
- R'--(SH).sub.x
- wherein x is at least one and R is an organic moiety.
- 3. The composition of claim 1 including an ionizable metallic compound wherein the metal is selected from Group I, II, III or VIII of the Periodic Table.
- 4. The process of forming a solidified, homogeneous mass which comprises admixing a plastisol composition comprising (a) a copolymer resin of a normal .alpha.-olefin and maleic anhydride (1:1 mole ratio having a particle size in the range from about 0.1 to about 1500 microns and having the structure ##STR13## wherein B is a member of the group consisting of ##STR14## R is H or C.sub.x H.sub.2x+1, x is 1 to 16 and n is 2-300, and (b) 65-600 parts/100 parts copolymer of a thiol plasticizer having the formula
- R--(SH).sub.x
- wherein x is at least one and R' is an organic moiety; and, thereafter, heating the admixture for a time sufficient to flux the mass.
- 5. The process according to claim 4 wherein the composition includes an ionizable metallic compound wherein the metal is selected from Groups I, II, III or VIII of the Periodic Table.
