Abstract
This specification discloses manufacture of copolymers of alpha-methylstyrene and styrene in which the alpha-methylstryene may range from about 50 to 90% and the softening point may range from about 60.degree. to 100.degree.C. The copolymers have especial utility with elastomers to produce pressure sensitive adhesives and the like, and in hot melt coatings.
Claims3
A hot melt composition comprising (i) a wax selected from the group consisting of paraffin wax and microcrystalline wax, (ii) ethylene vinyl acetate, and (iii) a copolymer of alpha-methylstyrene and styrene which copolymer has a softening point (ring and ball) up to about 100.degree.C.
