Claims
- 1. A process which comprises polymerizing an alkyl acrylate having an alkyl group of 1 to 8 carbon atoms and an alkoxyalkyl acrylate having an alkoxylalkyl group of 2 to 8 carbon atoms as polymerizable monomers with an organic peroxide having a non-conjugated double bond as a polymerization initiator, which peroxide is a compound represented by the following formula ##STR5## wherein R.sub.1 and R.sub.2 are a hydrogen atom or a methyl group and R.sub.3 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms.
- 2. A process according to claim 1, wherein an organic mercapto or organic sulfide compound having a double bond is used as a molecular weight-controlling agent together with said organic peroxide as a polymerization initiator.
- 3. A process according to claim 2 wherein said organic mercapto compound is a compound having the formula:
- R.sub.1 CH.dbd.CR.sub.2 CH.sub.2 SH
- wherein R.sub.1 and R.sub.2 are a hydrogen atom or a methyl group.
- 4. A process according to claim 2 wherein said organic mercapto compound is dihydrodicyclopentenyl mercaptan.
- 5. A process according to claim 2 wherein said organic sulfide compound is a compound having the formula:
- (R.sub.1 CH.dbd.CR.sub.2 CH.sub.2 S).sub.2
- wherein R.sub.1 and R.sub.2 are a hydrogen atom or a methyl group.
- 6. A process according to claim 2 wherein said organic sulfide compound is dihydrodicyclopentenyl disulfide.
- 7. A process according to claim 2 wherein said organic mercapto or organic sulfide compound is used in an amount of not more than 5% by weight on the basis of the polymerizable monomers.
- 8. A process according to claim 2 wherein said organic mercapto or organic sulfide compound is used in an amount of about 0.001 to about 1% by weight on the basis of the polymerizable monomers.
- 9. A process according to claim 1 wherein the organic peroxide as a polymerization initiator is used in an amount of about 0.01 to about 10% by weight on the basis of the polymerizable monomers.
- 10. A process according to claim 1 wherein the organic peroxide as a polymerization initiator is used in an amount of about 0.05 to about 3% by weight on the basis of the polymerizable monomers.
