## SYNOPSIS The grafting preference of vinyl acetate onto the methine carbon of poly(viny1 alcohol) (PVOH) versus the acetate group of poly(viny1 acetate) (PVAc) was determined as part of an attempt to prepare novel branched PVOH from partially hydrolyzed PVAc. The results showed long chain grafti
The kninetics of acid-catalyzed acetalization and ketalization of poly(viny1 alcohol) (PVA) were systematically studied in completely homogeneous media with carefully selected solvents. Thus the acetalization reaction was run in water with six aldehydes [RICHO (R, = H, CH3, CZH5, n-C3H7, i-C3H7, CIC
