METHOD OF ADHERING VINYL CHLORIDE POLYMER AND ADHESIVE FOR ADHERING VINYL CHLORIDE POLYMER

摘要

A method of preparing a cushion or like padded article comprising a plasticized vinyl chloride polymer cover filled with foam in which the cover is shaped and the foam prepared in situ within the cover, wherein a superior bond between the cover and foam is achieved by coating the interior surface of the cover prior to foaming with a primer composition comprising: (A) a latex of butadiene-acrylonitrile copolymer containing a hydroxyl or carboxyl group; and (B) a latex chosen from the group consisting of natural rubber, styrene-butadiene latex and mixtures thereof in an amount sufficient to promote bonding and wherein the weight ratio of (A) and (B) is from 4:1 to 1:4.
