Abstract
Abstract A method of manufacturing a water-based silicone type graft copolymer emulsion in which silicone (a macromonomer) having a radical polymerizable functional group and another vinyl monomer are, under presence of a surface active agent having a radical polymerizable functional group, emulsified and dispersed to a particle size of 0.5 μm or less, and the temperature is raised to copolymerize the emulsified and dispersed material. In the macromonomer, a macromonomer with a silicone structural unit repetition number n of less than 20 is contained in a quantity of 5 to 80 wt %.

Claim 1
Independent Claim
192 words
A method of manufacturing a water based silicone type graft copolymer emulsion consisting essentially of: emulsifying and dispersing in water a mixture of a first and a second silicone macromonomer having a radical polymerizable functional group and another vinyl monomer such that the particle size of the emulsion is 0.5 μm or less, in the presence of an initiator and a surface active agent having a radical polymerizable functional group, and raising the temperature to copolymerize the emulsified and dispersed material, and wherein said first macromonomer comprising the silicone structural unit repetition number N of less than 20, and said second macromonomer comprising the silicone structural units repetition member of at least 20, and said first macromonomer being present in a quantity of 5 to 80 wt %, based on total weight of said macromonomers said macromonomer being expressed by a Formula I: ##STR11## and wherein R is: ##STR12## and wherein R 1 is ##STR13## where Ph is phenyl group or alkyl substituted phenyl group; m is 0 to 10; n is 1 to 10 and with the proviso that: x+y+z=N, where x=0 to 150, y=0 to 150 and z=0 to 150.
