Abstract
An optical cement is prepared by forming a homogeneous blend of (1) 40 to 60% by weight of allyl phthalate, diallyl phenyl phosphonate or diallyl diethylene glycol dicarbonate; (2) from 60 to 40% of (a) an unsaturated polyester, (b) a mixture of an alkyl acrylate or methacrylate with 1 to 5% of a divinyl monomer, or (c) a mixture of 20 to 30% of an unsaturated polyester and 30 to 20% of a chlorinated biphenyl, and (3) a polymerization catalyst, heating to form a gel, cooling to room temperature, and homogenising with 25 to 1000% of its weight of the same blend in a more liquid condition. The preferred polyester is prepared from equimolar quantities of bicyclo (2,2,1)-5-heptene-2,3-dicarboxylic anhydride and 1,2-propane-diol. The more liquid blend may actually be a liquid or a soft gel and is homogenised with the firm gel by forcing them through a stainless steel screen. The cement is applied to the optical components and the assembly, without any need for a clamping device, is heated in an oven to polymerize the composition. Illustrated compositions are (1) equal parts of the above polyester and diallyl phenylphosphonate with 3% benzoyl peroxide; (2) as in (1), the allyl compound being replaced by diallyl phthalate; (3) 1 part of the polyester, 1 part of a chlorinated biphenyl, 2 parts of diallyl phenyl phosphonate and 3% benzoyl peroxide; (4) equal parts of n-butyl methacrylate and diallyl diethylene glycol dicarbonate, 1 1/2 % of a 75% p-divinyl benzene, 25% 1,4-ethyl vinyl benzene mixture, and 3% benzoyl peroxide.
