0.1 to 7 mW/cm2 until at least about 95% of the monomer has
been polymerized (col. 3, lines 34-47; col. 4, lines 6-8).
The acrylate-type monomers are acrylic acid esters of alkyl
alcohols, wherein the alcohols contain from 4 to 14 carbon
atoms (col. 3, lines 57-59), and the monomer mixture normally
contains from 70 to 98 parts by weight of the acrylate-type
monomer and 2 to 30 parts by weight of the copolymerizable
monomer (col. 3, line 67 - col. 4, line 4). Martens teaches
that he believes that the spectral distribution of the
irradiation and the rate of irradiation substantially
control the rate of polymerization, and that the rate of
polymerization determines the molecular weight of the
copolymer
produced (col. 4, lines 21-26). Martens states that use of
rates of polymerization higher than those used in his process
have been found to cause the copolymers to have unduly low
molecular
weights and to have sufficiently low cohesive strengths that
